VERY tough choice; Newspapers/other printed sources tend to be a little more accurate (not always, but slightly more so) than the other two choices, but it takes time to print. Television, though almost instantaneous, has severe credibility flaws when they try to sensationalize stories and assume too much information before checking facts. The internet provides accesibility to many more sources, so you can double check sources (if you know where to look), but any idiot with access to the internet can post crap and call it "news".
With all this in mind, I'll go with printed sources such as newspapers, with the criteria that I'd have to go with very specific sources, and keeping in mind that all things printed aren't necessarily true.
