Blogs, which started out as simple web logs that were updated daily, have evolved from basic, HTML-based online commentaries to full-blown online magazines complete with ads, streaming videos and sponsorships.

Traditional publishers question the accuracy of some blogs, and rightly so. Some people applaud the fact that blogs have taken the power of the media away from wealthy publishers and put it in the hands of journalists. Others say blog journalists aren't held to as high a standard as traditional journalists.
