From a recent press release:
"According to the latest results from Fairleigh Dickinson University’s PublicMind Poll, some news sources make us less likely to know what’s going on in the world. In the most recent study, the poll asked New Jerseyans about current events at home and abroad, and from what sources – if any – they get their information. The conclusion: Sunday morning news shows do the most to help people learn about current events, while some outlets, especially Fox News, lead people to be even less informed than those who say they don’t watch any news at all."
Fox News: worse than nothing at all.
