Does Apple announce the dates for their press conferences in public or just sends out mails to the different news companies?
The decision of when a press release goes out is internally made on a variety of factors. Public Relations is no longer what you see in traditional forms of media like radio, advertising or your daily newspaper. It is now enhanced by the Internet, by providers like PRWeb that send your press release to thousands of sources for a fee. It's easy to get the word out, as long as you use the right keywords and afflict the right target market.
