Prepositionally inclined About wants to be your online guru. The company's flagship About.com hosts a network of topic-specific websites grouped into content channels such as arts, hobbies, and sports on more than 78,000 topics. About.com features nearly 3 million articles created by some 900 human guides, or "topical advisors" -- which About describes as the "heart and soul" of its business. The free site generates revenue from advertisers trying to reach the 75 million monthly visitors. The firm also operates consumer product review site ConsumerSearch.com and diet site CalorieCount.com; along with About.com they make up the About Group. IAC/InterActive owns the company, which is now part of IAC's Ask.com.
