The 1980s wrestling boom (sometimes referred to as the 2nd Golden Age of Wrestling) was a surge in the popularity of professional wrestling in the United States of America throughout the 1980s. The expansion of cable television and pay-per-view, coupled with the efforts of promoters such as Vince Mc Mahon, saw professional wrestling shift from a system controlled by numerous regional companies to a system dominated by two nationwide companies: Ted Turner's World Championship Wrestling (WCW) and McMahon's World Wrestling Federation (WWF). 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.
