Fantasy Sports is a large and growing market who's core users align well with the Facebook demographic.  Current fantasy sports applications require users to reestablish their "social graph" on destination sites independent of  social networks.  Fantasy sports is an ideal application to be built on top of the existing social graph on Facebook.  Existing applications lack the necessary depth.   Millions are spent online in the US alone on fantasy baseball and football. Create a simple, easy to use yet fully functional fantasy sports application on top of Facebook.  FantasyBook gains customers by 1) appealing to more casual users and 2) incenting existing fantasy players to switch by providing the opportunity to integrate their fantasy sports experience with their existing social graph. The Company has built best of breed features from leading fantasy sports applications into a simple easy to use Facebook application.
