"Project Censored is a media research group out of Sonoma State University which tracks the news published in independent journals and newsletters. From these, Project Censored compiles an annual list of 25 news stories of social significance that have been overlooked, under-reported or self-censored by the country’s major national news media." Read more about them here.
Their top 25 stories 2002-2003 are listed here. This is a fascinating read, folks...I highly recommend it.
