Public Broadcasting Performance

I listen to MPR and NPR often. I like their programming, and I find that their political commentary programs strive to achieve balanced perspectives by inviting a variety of guests. I certainly prefer getting my news from NPR and my Google Reader than from television news programs. Plus, I hate commercials.

I found an interesting, though borderline outdated, report that supports my decision to get my news from NPR:

A study conducted in 2003 by the polling firm Knowledge Networks and the University of Maryland’s Program on International Policy Attitudes showed that those who get their news and information from public broadcasting (NPR and PBS) are better informed than those whose information comes from other media outlets, including cable and broadcast TV networks and the print media. In particular, 80% of Fox News viewers held at least one of three common misperceptions about the Iraq War; only 23% of NPR listeners and PBS viewers were similarly misinformed. (Wikipedia)

This is the article that Wikipedia cited: Pubcasting helps audience sort fact, fiction

Given that the article was published in Current.org, which discusses public radio and TV in the U.S., there definitely might be some bias present. I'd like to see a study that tries to determine what type of media consumers are the most accurately informed. What mix of media sources results in the most informed viewer/listener/reader? Moreover, are the habits that these most-informed readers have realistic for everyone? I strive to be well-informed on current political and scientific news by getting my information from a variety of sources. I have around fifty articles waiting for me each time I log on to Reader, and the radio in my minivan (don't hate on my minivan) is always tuned to NPR. I'm probably more informed than a lot of people. But I find it difficult to keep up with the news, let alone form opinions that I feel are supported by enough information.
