During its first three years of existence, Paris Saint-Germain Football Club were fan-owned and had 20,000 members. The club was run by board members Guy Crescent, Pierre-Étienne Guyot and Henri Patrelle. A group of wealthy French businessmen, led by Daniel Hechter and Francis Borelli, would then buy the club in 1973. PSG changed hands in 1991, when Canal+ took over, and then again in 2006, with the arrival of Colony Capital. Tamim bin Hamad Al Thani, the Emir of Qatar, has been PSG's owner since 2011 through Qatar Sports Investments (QSI).
