A press release is just what the name refers to. It is an article that explains the who, what, when,where, how and why of the story that you want to get out to individuals who may be interested. Nowa press release is by no means a sales letter and if written as such it is likely that it will be denied circulation in the media. The media, you mean the news will possibly pick my release up?
That's the beauty of a press release. If done effectively, it will attract countless news sourcesand inturn they will publish your story in a mediaoutlet.
