History of the Media, Radio, and Television

When were the forms of media created? When did advertising first show up? Who owns the media?

Creation of the various forms of media

*

History of the Media, Radio, and Television

Newspapers & Magazines ~ 1880

*

Movies ~ 1910

*

Television ~ 1945

*

Cable Television ~ 1980's

*

Satellite Television, Internet, Digital Communication ~ End of the 20th century

In 1920, radio was first developed, primarily for use by the military, strictly for sendingHistory of the Media - Old Radios messages from one location to another. David Sternoff, the then-president of RCA, first had the idea to sell radio sets to consumers, or what were then called radio receivers. However, consumers needed a reason to buy radios, so RCA was the first to set up radio stations all over the country. Between 1920 and 1922, 400 radio stations were set up, starting with KBKA in Pittsburgh. Stations were also set up by universities, newspapers, police departments, hotels, and labor unions.

*

By 1923, there were 600 radio stations across the United States, and million worth of sets had been sold.

The biggest difference in radio before and after 1923 was that the first advertising was not heard on the radio until 1923. RCA at the time was made up of four companies:

*

AT&T

*

General Electric

*

United Fruit

*

Westinghouse

United Fruit was one of the first global corporations, and one of the first to advertise on the radio. The AT&T division of RCA first thought about selling time on the air to companies, which marked the start of "toll broadcasting." WEAF was the first station to operate this way, causing widespread outrage, and accusation of "polluting the airwaves."

Because of this controversy, the practice of selling advertising time was called "trade name publicity." Sponsors linked their name with a program on the air, rather than advertising a specific product in a 30 second "commercial" as we know it today.

Why did AT&T decide to experiment with charging companies for air time?

AT&T was not making any money from broadcasting at the time since they only made transmitters, not receivers. They only made money when new radio stations bought the equipment required to broadcast. They did not make money from consumers buying radios.

AT&T also started the practice of paying performers for their time on the air, rather than only volunteers, which was standard practice for radio content up until that point.

The first radio network

In 1926, RCA set up the first radio network, NBC. They decided it was more effective and efficient to produce shows in New York City, and then link the main radio station with stations all across the country, connected by AT&T (another RCA company) phone lines. (Now television networks are linked by satellite to their affiliates).

This was the beginning of the network affiliates system. The ideal network makes sure everyone in the country is capable of listening to their signal. NBC at the time had two philosophies:

*

Radio content was a "public service," whose function was to sell radios.

*

Radio content was designed to generate income from advertising.

History of the Media In 1927, the second network was formed. It was CBS, started by William Paley. Paley was the first to think that networks could make money strictly from advertising, not even getting involved in the sales of radios. Like AT&T, CBS did not make radios. From the start, they made their money from selling advertising.

The rising of radio networks caused the Radio Act of 1927 to be passed, which established the FRC, or what is now known as the FCC, to allocate broadcast licenses. The need for such an organization was brought on by the fact that airwaves are limited resources, and broadcasting itself is a scarce public resource. By the 1930's, the structure of radio have been set by the commercial format, although advertising never dominated radio like it would television later on.

In the 1920's and '30's, radio programs were divided into two groups. Sponsored shows, which had advertisers, and unsponsored shows, which did not. The radio station paid for the unsponsored shows. The sponsored shows, on the other hand, were created entirely by the company sponsoring the show; advertisers were totally in charge of the radio station's content. The content became advertising. Radio set the precedent for television, in that the same companies that controlled radio early on went on to control television.

Soon thereafter, television inherited the structure of radio. In the '40's, during the rise of television, RCA also held a monopoly on all television sets sold. By 1945-1955, advertising had taken over all of television. Television was organized around the premise of selling things. The entire television industry was creating a political atmosphere of suspicion and fear. Senator Joseph McCarthy, the founder of McCarthyism, which was based on the fear of Communism, and the HUAC (House Un-American Activities Committee, began to question people involved in television about their beliefs and associations.

What affected television in its early stages?

*

Politics (McCarthyism / HUAC).

*

Blacklists: From almost the inception of television, many writers, directors, and actors were considered to be pro-Communist and/or un-American.

Certain topics were totally off-limits at the time for television, particularly issues of race relations in the 1960's. Overall, networks were not happy with the political situation for television in the 1960's, both in terms of the blacklists, and of the fact that when every show had one sponsor, that sponsor controlled the entire program. Networks preferred to control the program, by way of moving to multiple sponsors/advertisers, where networks would retain control of the show, and advertisers would buy time in between the programming.

In the 1950's, networks decided to eliminate the practice of sponsors controlling the shows with a move to spot selling, or advertisements between programs, as we know it today. What caused the move to spot selling?

1.

Discovery of fraud in the quiz shows on television. Quiz shows were extremely popular at the time, and were liked by the networks, the sponsors, and the viewers alike. It turned out, however, that quiz shows were largely fixed. Charles Van Doren on "21" became a huge star due to his repeated wins, until it came out that the whole thing had been fixed. In the case of "The ,000 Question," the owner of Revlon was personally hand-selecting the winners and losers on the show.

2.

It was becoming financially difficult for just one advertiser to support an entire show.

Around this same time came the inception of ratings to measure a show's popularity. Ratings, quite simply, measure the number of people watching a show. To understand why ratings are so important, it's crucial to understand how the television industry works, through three questions, and their respective answers:

1.

Who owns television? [The networks]

2.

What is sold on television? [Viewer's time, not television shows]

3.

Who are the customers of television? [Advertisers, not viewers]

This might be a counterintuitive concept for some. The networks, which own television, areHistory of the Media - Old Television the buyers of shows, not the sellers. On the other hand, they sell our eyeballs, so to speak, to advertisers. Networks want the maximum possible profit from buying and selling time, both viewers' time, and advertisers' time.

The primary measure of television ratings, which determine the price of that time being bought and sold, is AC Nielsen, an independent company which provides information as to who watches what on television. Currently, about 4,000 households are used to represent the national viewing of television. In the 1980's, only 1,200 households were used. Some households have an electronic device installed on their television which tracks what they watch, while others keep a diary of viewing habits.

There are two measures for determining a show's audience. One is the rating, and the other is the share.

*

Rating: Percentage of total homes with televisions tuned into a particular show.

*

Share: Percentage of those watching television at a particular time who are tuned into a particular show.

The share is always greater than the rating. Ratings are more important for advertisers, and share is more important to the networks.

Example:

*

Total households with televisions: 150 million

*

Total households watching television at 8pm on Monday nights: 90 million

*

Total households watching American Idol at 8pm on Monday nights: 45 million

*

Therefore: Rating: 30, Share: 50

It's important to note how many factors can skew the results. Shows cost producers much more than the networks typically pay them for those shows. The way for producers to make money is by getting the networks to renew the show, in order to have a shot at making money from syndication on other channels, also knows as reruns. That is the case when individual stations (say for example, the Miami affiliate of ABC wants to carry Seinfeld), buy the rights to a show from the producers of that show. Shows that last only one season, for the most part, lose millions of dollars. One of the most important factors in whether shows will be renewed or not is their rating.

This brings us to how ratings can be skewed. For example, if a show has a 20 share, and it needs a 25 share to be renewed for another season, what might the producers do? In principle, they need to convince another 5% of the people watching television when their show is on to watch their show; this is no simple task, as that involves convincing millions of people. However, since the ratings are based on those 4,000 Nielsen households, that means that they could convince just 200 Nielsen households to watch their show, which would increase the share from 20 to 25. This is why Nielsen households must be kept totally secret from the networks. When the Nielsen households have leaked to the networks, one way which they got people to watch their show was by offering viewers a small sum of money for filling out a survey about a commercial which they were told would play only during a particular show. Since they had to watch that channel while their show was on, this would boost the share.

Once ratings are determined, advertising prices are set by two factors:

* The size of the audience.

* The demographics (income, age, gender, occupation, etc) of the audience.

In short, the job of television programs is to collect our time as a product, which they then sell to advertisers. Programs have to support the advertising, delivering viewers in the best possible state of mind for buying when the time for the commercials comes, which brings us to the Golden Age of Television.

The 1950's are considered the "Golden Age of Television." During this time, something called the "Anthology Series," where different actors each week took part in a show gained History of the Media - I Love Lucypopularity across the board...that is, with everyone except for advertisers. The anthology series format was not right for advertisers, as it covered topics which involved psychological confrontations which did not leave the viewers in the proper state of mind for buying the products shown to them between program segments. The subject matter of the anthology series was of the type that undermined the ads, almost making them seem fraudulent.

This brought up the question of what to network executives actually want shows to do? The answer is not to watch a program that makes them feel good, makes them laugh, or excites them, but rather to watch the television for a set amount of time. With so many new shows being proposed, standards began to be intentionally, or unintentionally, laid out for what shows could and couldn't do. Risks could only be taken at the beginning and/or end of shows. Laugh tracks were conceived to tell the audience when to laugh. Programs began being tested with audiences prior to being put on television and/or radio. Show writers now had to write shows that would test well.

Naturally, this caused many of the same elements and themes to appear in all shows. This was the beginning of recombinant television culture, where the same elements are endlessly repeated, recombined, and mixed.

This same culture is what perpetuated the idea that people watch television, not specific shows. While people certainly choose to watch certain shows instead of others, people less commonly choose to watch television instead of other things. People watch television. Regardless of what was on, television viewing rates were extremely stable.

Doc... I've Got Severe Pain Between My Shoulder Blades - What's Causing It?

There are many causes of pain in the shoulder blades. Pain between the shoulder blades can occur as a result of mundane problems such as working at the computer too long without a break. Some causes though are serious and must be addressed immediately.

Here are some them:

Gall Bladder Pain

Doc... I've Got Severe Pain Between My Shoulder Blades - What's Causing It?

Sporadic pains in the middle of the upper abdomen, or just below the ribs on the right side are felt. The pain may spread to the right shoulder or between the shoulder blades. The pain can be accompanied by nausea and vomiting and sometimes excessive gas. The attack can last from a few minutes to two to three hours before getting better. The frequency and severity of attacks is very variable. Attacks can be triggered by eating fatty foods such as chocolate, cheese or pastry. It can be difficult to distinguish the pain from other diseases, such as: gastric ulcer, back problems, heart pains, pneumonia and kidney stones.

Neck source from arthritis or disc disease

This is a general pain located in the neck area and may be associated with stiffness in the neck muscles. The pain may radiate down to the shoulder or between the shoulder blades. It may also radiate out into the arm, the hand, or up into the head, causing a one-sided or double-sided headache. The muscles in the neck are tense, sore and feel hard to the touch. Acute pain can give rise to abnormal neck posture in which the head is forced to turn to one side; this condition is known as torticollis.
The pain at the base of the skull may be accompanied by a feeling of weakness in the shoulders and arms. There may be a prickly or tingling sensation in the arms and fingers.

Angina Pectoris

Angina pectoris derives from Latin and translates as 'tight chest'. It feels like a heavy, crushing pain or a constricting feeling in the center of the chest behind the breast bone (sternum) or on the left side of the front of the chest. The pain can radiate out to either one or both arms, more often the left. It can be experienced in the throat, jaw, the stomach and, more rarely, between the shoulder blades.

Angina is often brought on by:

o physical exercise

o psychological stress

o extreme cold

o a heavy meal.

Once these trigger factors stop, the pain generally ends quickly, usually within 2 to 10 minutes.

Liver Cancer

Liver cancer, an abnormal cell growth in the liver presents in two ways:

o Primary cancer means that the cancer started in the liver

o Secondary cancer of the liver occurs when a cancer starts someplace else and spreads to the liver.

The early warning signs of liver cancer:

A hard lump in the abdomen, below the rib cage on the right side.

Discomfort in the upper abdomen on the right side.

Pain around the right shoulder blade, or pain between the shoulder blades.

Yellowish skin color (jaundice)

Abdominal swelling causing a feeling of fullness

Esophageal Cancer

Esophageal cancer appears as a tumor, or an abnormal growth of cells in the esophagus. The esophagus is the food passageway that connects the throat to the stomach.

Esophageal cancer usually does not cause any symptoms until the cancer has advanced to a stage that is too late for effective treatment. The main symptom is difficulty in swallowing food. There is a frequent sensation of food getting stuck in the throat or chest.

Signs of advanced esophageal cancer include:

Pain when swallowing.

Pain in the throat or back, behind the breastbone or pain between the shoulder blades.

Decreased appetite and weight loss.

Hiccups with the feeling of food getting stuck in the throat or chest.

Vomiting and coughing up blood.

Aortic dissection

When the aorta, the major artery leading from the heart, tears, there can be sudden sharp pain in the spine between the shoulder blades. This is an obvious surgical emergency.

How To Become a Computer Technician

So you want to be a Computer Technician, but you don't know how? Well guess what, I am going to tell you how.

First things first, I am blunt and to the point. I hate typing and thinking about grammar, that is why I went into the Technology field.

I have over 10 years experience in web design, computer networking, hardware, software, java programming, Apple & IBM (pc) format computers, telephone work, home theatres etc, etc, etc, & I make a lot of money doing. So basically I know what I am talking about & I am going to give you some advice that took me 10 long, hard years to learn.

How To Become a Computer Technician

1. MOST IMPORTANT: LEARN how to find the right answers. This can be true for ANY field, ANY person works in. You do not need to know everything, and guess what, if you spent the next 10 years reading, going to school & obtaining certifications, you still wouldn't know all there is to know in the field of Technology. But if you can figure out what resources will help you find a solution for you the fastest, then you are on your way.

2. Go to school and/or get certifications. Of course you need to learn about computers, software, hardware etc to become a computer technician. Find something that fits you, something that makes you excited to go. 4 year schools are not for every one, so make sure they are right for you if you choose to go. In my 4 years in college the only thing I learned to do is program at Level II in Java (a blind monkey could program at that level) and drink a lot of beer. 2 year schools are good because the get straight to the point about the actual jobs you will be doing out in the REAL world. (I was offered a teaching position at one of these 2 year schools at the ripe old age of 25, I laughed in their face & said no because of the salary they were offering). Certifications are important regardless if you get a 2 or 4 year degree. They tell other people that have NO CLUE about technology that you, indeed have a clue about technology

Did you follow that?

A couple of certifications that I highly recommend are the A+, Networking + and any Microsoft Support Certification.

3. Be patient, with yourself and the people you work with. You will always be learning if you become a computer technician. The average lifespan for a particular model of technology (ie computers) is about 2 years. Meaning as soon as you buy it, it is OLD. Things change everyday in Technology and you have to keep up with it!

4. Have a Positive Attitude! Remember, when people call you or you are dispatched out to work on someone's computer, TV etc, they usually are frustrated. Most people will try to fix the issue themselves before calling anyone because they are cheap. By the time you or I get there they are ready to cry. A positive and friendly attitude will go an EXTREMELY LONG WAY. You will be their savior and they will tell all their friends about you. This point might be the most difficult, especially in Technology because not very many people understand how it works and because our lives are so dependent on it.

That is it, 4 simple steps.

Can you handle it?

These are the 4 things I have tried to do over the last 10 years. Trust me, I am no genius, not by a long shot. But I figured out how to find the right answer for the problem, combined with an education, some certifications and the right attitude, I have people knocking down my door for my services.

Read this article a couple of times until this info really sinks in. This advice works so use it!

Stop sitting there and get busy!

For more information on How To Become a Computer Technician, check out a couple of this sites I have listed in my bio, those will help.

Good Luck!

Writing a Request For Proposal For Web Site Design and Development

A company that is looking to get bids from several qualified vendors for a Web site design or development project will typically write a Request for Proposal (RFP) and either post it online or send it directly to potential vendors it has identified.

As with any complex project, a Web site design project requires clear communication between the client and web developer in order for the client to receive accurate bids. The RFP serves as a baseline of project requirements on which competing vendors may price their services. I have outlined a few items below that should typically be in a Website Design and Development Request for Proposal, though some times more information is necessary.

Writing your Request for Proposal

Writing a Request For Proposal For Web Site Design and Development

The Request for Proposal (RFP) process allows potential vendors to get an idea of your goals, existing challenges and possible limitations without lengthy phone discussions or in-person meetings that can severely impact the amount of time it takes for you to get started with your Web Design and Development project. It allows you to succinctly describe exactly what you are looking for and what a potential vendor should expect in the project.

An ideal RFP would clearly specify all the requirements pertaining to your website. It would allow the developer to present you with a proposal based your particular needs and, needless to say, the more details your RFP contains, the more accurate a proposal the developer is able to present.

Components of a Request for Proposal (RFP) for a Web site Design and Development Project:

Project Background Information

Brief overview of your organization, including some history and your primary business objectives. Detailed description of the project you would like to receive the proposal for. If your budget requirements are strict, it might help to include a 'Ballpark' Budget - which developers can use to scope and scale your solution and save you time. Target launch date and required deliverable dates - include any dates that you need the project to meet. Are there crucial meetings and cut-off dates that the developer should be aware of? If you are not sure what the time frame should be, it's okay to see what the proposals you receive recommend and renegotiate. It's also good to anticipate and state how flexible you are with the project's completion date.

Marketing Requirements and Data

Audience demographics - who will be the main users of your site? Are there several different audiences that need to be addressed? User comfort level with technology -  how technically savvy is your audience? Will they know how to deal with plug-ins, for example? Will users have high-speed connections, or will many be on modems? Audience base -  how large do you expect your user base to be?

Design and Corporate Branding Requirements

Do you have corporate identity guidelines that must be followed, including fonts and colors and graphic treatments? What look and feel to you envision for the Web site? Include some adjectives to describe what your site should communicate. Provide examples of Web sites that relate to the RFP either because they have a similar feel to the one your are looking for, or even examples of what you do NOT want. Will there be any animated elements (i.e. Flash animations)? How many? How are they going to be used?

Technical and Infrastructure Requirements

Web hosting considerations. Do you currently have a Web host or are you looking for a new one to handle this project? Browser/platform considerations. Generally speaking, a Web site for consumers or the general public should work similarly across all modern browsers and Operating Systems. If you are targeting a very specific audience it is possible your needs are different. Development platform requirements. Do you require an Open Source solution, are you open to a proprietary solution that is more tailored to your exact needs, etc. Coding language requirements (e.g. ASP.NET, PHP, Java). Many times this depends on the type of Web hosting platform or any pre-existing software you may have. Are there third party applications you'd like to incorporate?

Functionality/programming Requirements

Will there be forms on the site? If so, how many? How should they be handled? (e.g. e-mailed to recipients, stored in a database, etc.) Will the site require tools to manage content/information (e.g. ability for staff to add content such as press releases or quarterly reports)? Will there be any e-commerce on the site? If so, who will be entering data on products offered? How will transactions be managed? Are there any other interactive features the site should have? What are they, and how do you envision them to work?

Search Engine Optimization

Describe any currently defined search engine friendly production requirements and expectations Indicate if you are seeking SEO/SEM consultation services

Ongoing Site Maintenance Plans

How often will the site be updated? Are you looking for a retainer situation, or 'on-demand' hourly work? Will you be self-maintaining or will you be outsourcing maintenance services?

Project Management

Who will be the main point of contact on your staff? Keep in mind that in most cases it is easiest to have a single point of contact at both your organization and the company designing and developing your Web site. How will the tasks be divided between you and the developer in order to complete the project? Are there any third parties (subcontractors, etc.) that will also be involved in the project?

RFP Response Deadline and Contact Information

When is the response to the RFP due? To whom should the response be sent? Do you prefer E-mail or hard copies, and if so, how many hard copies? Is there a specific solicitation number that needs to be referenced in the Proposal Document? What is the RFP review process? How long do you anticipate to take to make your decision before the project can begin?

Some Additional Thoughts Before You Begin:

For all items listed above, be sure to clearly indicate if you must have any item(s) bid as an optional aspect of the project. Keep in mind possible dependencies between project aspect/components that may make this impractical. Before writing your Request For Proposal, determine your budget for the project and, beyond that, your priorities for selecting a Developer who can meet your budgetary requirements.

Writing an RFP is a good exercise for anyone thinking about a site design or redesign as it takes thoughtful planning to specify and construct a website. A well thought out, quality RFP is essential to a successful endeavor because it helps you to focus on your goals and exactly how to achieve them.

Best of luck with your Web site Design and Development Project.

How to Fix VBA Runtime Error 1004 for Excel Macro Programming

Runtime error is quite common, and you might have experienced it while working on the computer. The Runtime Error 1004 is caused when you copy and paste the desired data to the MS Excel worksheet. Users are programming some VB macros to calculate the complicated formulas, as a mini application. When this error happens, the Microsoft VB fail to work out the commands or transfer data that is filtered. This entails that you should change the data which you prefer transferring or you should find an alternative method to get it done. The usual format of the runtime error code 1004 will be: "Copy function of the Range Class failed" or "Paste method of work book classed failed".

The major rationale of this runtime error is due to the VB application trying to copy the complete row and paste them into the worksheet or it might try to too many rows into the Excel worksheet. To resolve this runtime error, you must first ensure that the VB macro is right transferring to the defined row to the Excel worksheet. Rather copying the complete row, you could get it done by a simple command usage. Doing so, the data will be transferred to the system without leaving any piece of information.

Once after doing this, you must clean your windows registry. We all know that windows registry is an important unit of your computer and stores the desktop images, wallpapers, latest data updates and besides this, it also stores the computer settings too. When any files or applications in the registry are damaged, it will result with major disasters and might wreck your system together. Keep in mind, windows registry should not be edited or aligned manually rather you should use the registry repair tool to perform the operations.

How to Fix VBA Runtime Error 1004 for Excel Macro Programming

The use of registry repair tool will completely remove the errors and it fixes the runtime error 1004 easily and effectively. This registry repair tool not only helps in resolving the error code 1004 but also helps in troubleshooting a variety of errors that is caused due to registry damage. It will detect the errors and fix them as well. Don't try to edit the registry yourself if you don't have good knowledge in handling the issue, but try a registry tool. If you don't have this tool in your machine, you can download it online. Since it is free of cost, anyone can download and use it to clean the computer thoroughly. However, the paid one is always providing the better and more reliable functions as needed.

BlackBerry Programming 101 - How to Get Started With BlackBerry Software Development

The success of newer BlackBerry models like the Pearl, Curve, Bold and Storm have allowed RIM (Research in Motion) to penetrate the consumer smartphone market and go head-to-head with the Apple iPhone as an application platform. If you've been ignoring the BlackBerry platform because it was too Enterprise-focused for your applications, it might be time to specifically target the BlackBerry. Here's how you get started.

It's Java Time

BlackBerry development for all recent models is done exclusively in Java. So if you're not a strong Java programmer, now's the time to brush up on your Java programming skills. (C# programmers will find the transition to Java fairly simple, the languages are very close in most respects.) Don't learn about the newest Java features, however, because the BlackBerry platform is built on top of Java Micro Edition (Java ME), which is itself a derivative of Java version 1.3. So forget all the fancy (but useful) language features introduced in Java 1.5 -- generics, enumerations, and so on -- you can't use these in BlackBerry programming. You can't also use most of the library classes you're familiar with -- they're just not there. A small subset of the Java Standard Edition (Java SE) classes are supported, as well as a number of BlackBerry-specific classes.

BlackBerry Programming 101 - How to Get Started With BlackBerry Software Development

Java Micro Edition?

Once you've brushed up on your Java, you need to spend a bit of time understanding the Java ME platform, which was formerly known as Java 2 Micro Edition, or J2ME for short. You need to understand the concepts of configurations and profiles, and in particular the CLDC and MIDP standards. You'll find lots of information about these in various books and on Sun's Java development site.

The BlackBerry Platform

After learning about Java ME, it's time to explore the BlackBerry platform. The BlackBerry platform is based on the CLDC and includes support for MIDP 2.0. However, a large number of BlackBerry-specific classes are also provided. Which brings you to the first question you'll face: are you going to write a BlackBerry application or a MIDP application? In a MIDP application you're constrained to only use the APIs exposed by the CLDC and MIDP standards. Your application will run on the BlackBerry and on most cellphones, but it won't be able to use any of the BlackBerry's special features. You can use any MIDP-compatible development tool, such as the Sun Java Wireless Toolkit for CLDC (formerly known as the J2ME Wireless Toolkit), to create your applications.

Most application developers opt to build BlackBerry-specific applications. This means learning the BlackBerry-specific APIs -- including new user interface classes -- and using the BlackBerry Java Development Environment (JDE) to develop your applications. The JDE, which is free to download, works with the standard Java Software Development Kit and provides you with all the tools necessary to create, package, test and debug BlackBerry applications. You don't even need a BlackBerry handheld, because the JDE includes a full-featured BlackBerry device simulator. A complete set of JavaDocs is provided that describes all the classes and interfaces available to programmers.

After downloading and installing the JDE, you'll want to read the developer's guides that come with the JDE and look at the sample applications that are shipped with it. Then start your development by writing a few simple applications to get a feel for the BlackBerry APIs and the tools.

Get A BlackBerry Handheld

Although you can develop and test your applications for free, at some point you'll need to run the application on an actual BlackBerry handheld. This will cost you money, of course, and so it's not something you'll want to do until you're serious about writing BlackBerry applications. On-device testing is crucial to ensuring that the application works correctly, because the simulator is not a perfect emulation system.

If you're truly serious about BlackBerry application development, consider also joining one of the BlackBerry developer programs for additional support and early access to new devices and APIs. You should also explore RIM's other BlackBerry developer resources. There are also third-party forums and books available to help you learn the BlackBerry platform.

Conclusion

BlackBerry programming is not hard if you know some Java and you understand the constraints and limitations of the underlying Java ME platform. You have to learn a new set of APIs and use new development tools, but in the end it's just another kind of Java programming.
