Red Network, while rival WMPS, owned by the Memphis Press-Scimitar, aired the NBC Blue Network. Starting in the 1930s, the station used a riverboat whistle as its sounder, a nod to Memphis' location on the Mississippi River—a practice that continued well into the 1990s. WMC added an FM sister station, WMC-FM, in 1947 and a TV station, WMCT (now WMC-TV), in 1948. Because WMC was an NBC Radio Network affiliate, WMC-TV also affiliated with the NBC TV Network, which it still carries to this day. During the 1960s, WMC had a middle of the road format of popular adult singers (known in the industry as MOR). In 1973, WMC became the first 24-hour full-time country music station in Memphis and was often #1 in the ratings. By the 1980s, music listening was shifting from AM radio to FM and in 1983, 105.9 WGKX (KIX 106) went country as WMC's first full signal FM country competition. By 1989, WMC switched to news/talk. An NBC radio affiliate since 1927, WMC switched to CBS Radio News in 1994. In 1997, "News/Talk 790" gave up Rush Limbaugh to rival 600 WREC as well as its morning news show. In July 2001, WMC made the switch to all-sports as "Sportsplus 790." The Good Times Show, with news about casino gambling in Tunica, Mississippi, made its debut on the station at that time. In December 2005, CBS Radio changed WMC to a classic country format, because the Memphis radio market had many competing sports stations Most programming was provided by Jones Radio Networks' Classic Hit Country network, which subsequently became Dial Global's Classic Country network. The station returned to an all-sports format on October 17, 2011, taking the Fox Sports Radio affiliation from 730 KQPN. On May 1, 2014, WMC picked up the ESPN Radio affiliation (rebranding as "ESPN 790") in addition to its current CBS Sports Radio affiliation. On December 9, 2021, WMC changed its affiliation to a combination of BetQL and CBS Sports Radio as "The Bet 790".
