Demand Media, Inc. is an American content and social media company that operates online brands such as eHow, and Cracked, and is known for creating online content through its Demand Media Studios division based on a combination of measured consumer demand and predicted ROI. Demand Media's business model is controversial because their "content farms" have been accused of polluting search engine results with spam. The company also provides social media platforms to existing large company websites and distributes content bundled with social media tools to outlets around the web. The company also owns eNom, the world's second-largest domain registrar, and as of 2013, the most abused/abusive registrar of domains used for spam email, according to URIBL. Demand Media was created in 2006 by a former private equity investor, Shawn Colo, and the former chairman of MySpace, Richard Rosenblatt. The company employs an algorithm that identifies topics with high advertising potential, based on search engine query data and bids on advertising auctions. These topics are typically in the advice and how-to field. It then commissions freelancers to produce corresponding text or video content. The content is posted on a variety of sites, including YouTube and the company's own sites such as eHow, Livestrong.com, Trails.com, GolfLink.com, Mania.com, and Cracked.com.
