The WWF held 13 pay-per-views in the 1980s if you include No Holds Barred. They first hit pay-per-view with WrestleMania I, then quickly followed that up with The Wrestling Classic in late-1985.

Using 'Mania IV as a bartering tool and effectively holding PPV providers hostage was a hostile but genius move from the WWF's higher ups. They knew they had one hell of a bargaining chip there.
