Many of the big sites, like, say, Flixster, uses BusinessWire.com. Example: http://www.businesswire.com/portal/...d=news_view&newsId=20100104005980&newsLang=en
pr-usa.net is a good one, but like many free press release sites, you will need to ensure that your release is of a certain quality level. For maximum impact if your budget allows, I recommend PR Newswire for premium level releases.
I would recommend, as always, the following best ones - prweb, marketingwire, prnewswire, businesswire. PS. All are paid services.
There's a great list of press release sites here: http://www.subhub.com/articles/the-best-free-and-paid-press-release-websites-and-when-to-use-them
Depends on what you want. There are free and paid press release sites. Some paid press release sites really charging too much!
