You might group CNN/MSNBC/FOX all together because CNN is a rather glaring omission and they're all 24 hour cable news channels with many of the same idiosyncrasies. Despite the large ideological divide between MSNBC and FOX, they are quite similar in a number of ways.
Honestly, C-SPAN and Al-Jazeera (English) could afford to be on there as well. I doubt there'd be significant support for Al-Arabiya, though I could be wrong. But you have limited space and wasted two slots on fake news programs with the same executive producer (Jon Stewart) and a third on the channel that they both appear on. They also both tend to cover the same news. That one could afford to be one category, and maybe include other late night talk shows.
"Newspapers" is overly broad, and it is unclear whether it would cover news magazines like the Economist, Foreign Affairs, etc. as well. There's also a whole heap of difference between for instance the Seattle Times, and better national newspapers like the New York Times or Wall Street Journal.
I would do this:
American Cable News (FOX/MSNBC/CNN/C-SPAN)
BBC
Al-Jazeera (English language version)
Late Night Talk Shows (TDSwJS/Colbert/Kimmel/Conan/Fallon/Leno)
News Magazines (Economist, etc.)
National Newspapers (NYTimes, WSJ, Washington Post)
The Local Newspaper (because the trend is that there's only one...)
Escapist... or other online sources (blogs, Google, fark)
I'm not really satisfied with this list either because I very much doubt that BBC is the only British news channel (Sky or something?) and for the sake of completeness I've pulled lots of different things together while still not filling out the complete selection. I mean, hell, there's even the regular news programs like NBC Nightly News, Newshour with Jim Lehrer, ABC, CBS and so on. I suppose you could perhaps scrap Al-Jazeera or "the local newspaper" in favor of Nightly News shows. You could be even more simplifying and do this:
Internet
Television
Print
or
24 hour cable News
Nightly News
Comedy Newsish Programs
Print News
Online News
Anyway, there is virtue in a poll for having categories of roughly equal stature.
