Now days press releases are emailed and I think it gets better results. But you don't have to have a press release to get media attention. Simply email your idea or information in a brief message. Include your contact info so the reporter can follow up with more questions. Almost all media have a Web site complete with contact email addresses.
Editors often appreciate a quick phone call from anyone with good information to share.
Make sure your info matches the media outlet's audience interests. Don't bore a busy reporter with preliminary details.
