Kelley Blue Book helps steer people away from something yellow -- a lemon. The company publishes information on vehicle pricing, including automobile trade-in values, as well as car ratings, reviews, and news. While the company still publishes the traditional print Blue Book Official Guide, it has shifted its focus to the Web, offering all of its information online. In addition to vehicle values and reviews, the Kelly Blue Book website offers tools for used and new vehicle searching, as well as dealer price quotes. It also offers car videos and a mobile app. The company was established in 1926 by car buff Les Kelley. It was acquired by online automotive advertising company AutoTrader.com in late 2010.
