If you offer a percentage of sales on your CD to the Save the Rain Forest organization, perhaps environmental publications would find your news worthy of printing. They do not owe you a story, so you must make it interesting. If you can send news that will appeal to the readers, you are far more likely to get printed. The free publicity you generate with your press release will be many times more valuable than any advertisements you could buy. Studies have shown that people respond to articles at a much higher rate than ads, because they are perceived to be more credible.
Most press releases follow a similar format, and it's easy to learn.
First, spend some time defining the Main Message you want to get across. You will need to tell the who, what, when, why, and where in your press release. Many people suggest double-spacing your type, as well as leaving a minimum 1 inch white border on all sides. Use an easy to read font. You can use any simple word processing program to build your release, and print it on any decent computer printer.
