At the end of every season, financial donations are made to charities designated by winning teams. As of March 2015, over $2,611,440 have been donated to teams' charities. ZogSports was founded in 2002 by Robert Herzog, after he survived the September 11 attacks. Herzog worked on the 96th floor of the World Trade Centers North Tower as a vice president of operations for Marsh & McLennan. Herzog says he was inspired by the altruism he witnessed after the attacks and decided to incorporate charity as a major component of ZogSports. In its first season, ZogSports had 500 participants. As of June 2014, ZogSports has over 115,000 annual participants, making it the largest co-ed, recreational sports league in the United States.
