When and why did pitch invasions/court-storming/rushing the field end in professional, american sports? I see highlights in the 70s from Hank Aaron's 715, Yankees winning their division, even the Celtics winning an NBA championship in the early 80s where the fans celebrate with the players (or try to take hats off of their heads). In my sports lifetime,(post 1992), I cannot recall a single moment of this happening in pro sports (in America).
Are there major concrete breakpoints in film quality/style over there years? Or are these more to do with the film to video conversion (I watch movies on television). Or are these perceived changes based on my historical memory? [more inside]
