There are 4 main newswire services. PRNewswire.com, Businesswire.com, PRweb.com and MarketWired.com. I have used them all over the past 27-years as both a journalist and PR/media relations expert.
Marketwired.com is the best because they are the most affordable and provide a great analytics report on where the press release went, how many people read it and how many clicked on the URL links in the press release.
It will cost around $250 for 400-words of text and one free logo. They sell extra blocks of words, video attachments and photo attachments for $50 to $125 each. If it is a big city like New York or LA, it will be more like $390.
You maybe tempted to use a free or very low cost wire service, but these are the wire services that fraudulent companies use so most reporters will ignore them simply because it take too much time to verify the companies.
Established companies always use one of the big 4 newswires.
Press used to be delivered by main frames to dumb terminals, known as buying a circuit. But in today's world press releases are feed by RSS feeds and where they go are determined by language and search engine optimization (SEO) keywords used in the headlines and first paragraph.
Press releases are still used by lots of reporters and bloggers, but now you can write a release specifically to reach your target audience of potential customers directly.
