CDM Fantasy Sports Corp. dba Fanball (Fanball, www.fanball.com) is a Liberty Media (www.libertymedia.com) company and was established on December 24, 1991, with the goal of becoming the largest operator of fantasy sports games in North America. Fanball consists of the assets of three companies that were acquired by FUN Technologies in 2005 and 2006. Liberty Media acquired 100% of FUN Technologies in December 2007. The first acquisition was Fanball.com, based in Minneapolis, MN, in 2005, the second acquisition was Fantasy Sports, Inc. (Fantasy Cup), based in York, PA, also in 2005, and finally the acquisition of CDM Fantasy Sports (CDM), based in St. Louis, MO, in 2006.

Fanball focused on two areas of fantasy sports leading up to the acquisition in 2005. The first area of focus was fantasy sports content and the second was a football commissioner service. Since its inception in 1995, Fanball has been a leader in both of these areas of expertise. Fanball's fantasy sports magazines and online fantasy sports news and notes are award winning content products. Fanball's football commissioner service is one of the largest subscription-based commissioner products in the industry.

Fantasy Cup is one of the largest operators of NASCAR-based fantasy sports games and content. Since its inception in 1993, Fantasy Cup has focused on offering a wide variety of fantasy auto racing products, having worked with both NASCAR.com and the Speed Channel over the years to grow their base of rabid fantasy auto racing fans.

CDM is the largest operator of salary cap fantasy sports games in the industry. CDM offers salary cap and other fantasy sports contests in baseball, football, basketball, hockey, golf, and auto racing. Since 1991, CDM has awarded over $50,000,000 in cash prizes.

Through the years, Fanball has operated fantasy sports games, investment games, celebrity games, and other contests by phone, mail, and the Internet on behalf of major media brands such as USA TODAY/Sports Weekly, Baseball Weekly, USATODAY.com, The Hockey News, Comcast, The Golf Channel, Pro Football Weekly, NASCAR.com, PGATOUR.com, The Excite Network, Primedia Specialty Group, The Sports Network, MSNBC, and The Sporting News with over 3,000,000 customers.
