Look for Unofficial Sources, Too

Don't get hung up in looking only to the leading providers of business information when doing critical business research. One of the great things about Internet research is all the nooks and crannies of information you can find. Business bloggers and business forums, for example, are unofficial news sources but they also cover businesses and industries with a level of detail that the leading publishers of business information don't usually offer. Business bloggers and forum participants are also generally on top of big news when it's still in the rumor stage and can give you a jump on that information -- even if you have to check it elsewhere for accuracy first.
