Lacking a big passionate fanbase, the club began offering cheaper season tickets to young supporters in 1976. These fans were placed in the Kop K, located in the K section of the Borelli stand at the Parc des Princes. Following an increase in ticket prices, Kop K supporters moved to the Boulogne stand in 1978, and the Kop of Boulogne (KoB) was born. There, the club's first Italian-style ultra group, Boulogne Boys, was founded in 1985. Other KoB groups, however, took British hooligans as dubious role models and violence rapidly escalated. PSG supporters' groups have been linked to football hooliganism ever since.
