Who Owns the News Media? website includes data re market share

The Who Owns the News Media? website http://stateofthemedia.org/media-ownership/ includes data about market share of companies over the news media in all formats. You can compare companies across media sectors. Plus do much more. The website is an outgrowth of the Pew Research Center's Project for Excellence in Journalism. Thanks to Lee who found this on the Resource Shelf Blog and shared it with us.
