The 1980s professional wrestling boom (more commonly referred to as the Golden Age) was a surge in the popularity of professional wrestling in the United States and elsewhere throughout the 1980s. The expansion of cable television and pay-per-view, coupled with the efforts of promoters such as Vince McMahon, saw professional wrestling shift from a system controlled by numerous regional companies to one dominated by two nationwide companies: McMahon's World Wrestling Federation (WWF, now WWE) and Ted Turner's World Championship Wrestling (WCW). The decade also saw a considerable decline in the power of the National Wrestling Alliance (NWA), a cartel which had until then domineered the wrestling landscape, and in the efforts to sustain belief in the verisimilitude of wrestling.
