 Professional wrestling began to become mainstream, thanks, in large part, to the appeal of Hulkamania among children.Large television networks also took wrestling into their weekly programming, including "Saturday Night's Main Event", premiering on NBC in 1985, the first wrestling show to air prime time since 1955.ESPN also began airing professional wrestling for the first time, first airing Pro Wrestling USA shows—which were created as an alliance between the NWA and AWA in 1984, in an effort to counter the national success the WWF was gaining—and later AWA shows, after Pro Wrestling USA fell apart by 1986.
