Count me among those who believe there is very little in the way of censorship – self-sensorship is another story, and I would prefer just to refer to it as bias.
If you are looking for media without bias, good luck! All media shows bias, it’s part of human nature. Even if the particular newspaper or other media source doesn’t show much overall bias, individual reporters can’t help but shade their look at the news based on their personal past experience. (Although the better ones will try avoid showing bias.)
It is better for us, as consumers of news, to try to at least be aware of the biases of those who report the news. I try to read from sources on both the conservative and liberal sides in order to get as many views as possible on a subject, and then form my own opinions.
If you are trying to find news that is little-reported and mostly ignored by the mainstream press, you might try:
(You can make up your own mind about whether these are biased more to the right or left)
Project Censored is a look at under-reported news, produced by Sonoma State University.
Mother Jones – self-procaimed muck-raker. Broke the Ford Pinto story and many other well-known cover-ups. Once had great series on the additives to cigarettes (including how removing the additive that keeps the cigarette burning while not being puffed on would save thousands of lives per year) and lost large amounts of advertising money.
Jim Romanesko’s Obscure Store and Reading Room – little-reported news that is probably deservedly so!
But also has numerous links to news sources
The News Insider – calls itself your “daily source for under-reported news and analysis”.
NewsWatch Canada – college-sponsored, similar to Project Censored, with a Canadian outlook.
Between The Lines – the web page of a nationally-syndicated weekly radio newsmagazine that reports on under-reported news stories. (This site is temporarily down for upgrading.)
Committee to Protect Journalists – if you are looking for censorship at the source, this might be the best place. They list reporters killed while reporting and arrests of journalists. They also issue the Press Freedom Awards to journalists who have risked their lives to get the stories out.
