How to search for popular press releases

[StreetwiseReports]

I would like to research popular press releases in my industry. Ones that got picked up by many popular outlets, got a lot of coverage etc. Besides mindlessly searching the web for press releases, is there a better way? Almost looking for a service that ranks press releases in terms of effectiveness.

I don't think I have ever seen any data for "the most viewed" press releases. Some of those free press release websites might have a public view count, but sites like prnewswire or prweb etc, I don't think they do.
