www.news.google.com from Google will give you a more specialized news media search than Google.  
www.daypop.com will narrow your media search even more than news.google.  
Subscription Search Engines have respected information.

Encyclopedia Britannica www.eb.com costs $60 a year.

www.worldbookonline.com cost $50 a year and serves a younger audience..
"GuruNet, a $30 subscription service, is another route to authoritative information, providing quick access to a variety of standard reference works, from the American Heritage Dictionary to Wolfram Research's online science and math encyclopedias. With GuruNet, searching doesn't require clicking on your browser -- and the results are ad-free. The program installs a small piece of Windows software. (A Mac version is due later this year.) After that, you can call up a reference simply by alt-clicking on any word on your screen or by entering a search term in a toolbar that hides at the edge of your desktop. Either way, a window pops open with basic information on the topic and choices for additional data. For example, a company name will give you company news and a stock quote, while a technical term will get a definition and an encyclopedia entry. GuruNet offers a fun feature for the intellectually curious by including Princeton University's WordNet lexicon. Like a dictionary, it gives definitions, but it also provides links to related terms or concepts, producing chains of information that can lead you far afield of your original query."
