from being a National Broadcasting Company (NBC-Red) affiliate and joined the Columbia Broadcasting System (CBS). At that time, WHAS operated with 10,000 watts of power, but the output was soon increased to 25,000 watts as authorized by the FRC. On March 29, 1941, a second major reallocation, as part of the implementation of the North American Regional Broadcasting Agreement, resulted in WHAS's clear channel frequency being shifted to its current assignment of 840 kHz. The station was originally part of the local media empire ruled by the Bingham family, which also published Louisville Courier-Journal and Louisville Times (now owned by the Gannett Company and merged in 1987) and operated television station WHAS-TV (which, following several mergers and transactions in subsequent years, is now owned by Tegna). WHAS and its FM sister station, WAMZ (the former WHAS-FM) were acquired by Clear Channel Communications (which, as iHeartMedia, continues to own the stations to this day) in 1986 as part of the breakup of the Bingham family's media properties. Programming evolution WHAS modernized in the early 1970s from an old-line MOR music outlet into an early form of Hot Adult Contemporary music format, featuring adult-appeal Top 40 hits and rock oldies; one longtime slogan was "Good and Gold" (as in "good music", or adult contemporary, and "golden" oldies). For a time in the 1980s, it was also the Louisville affiliate for Casey Kasem's American Top 40. The station continued to feature a full-service Hot AC format through the 1980s (and was the last 50 kW AM station with a full-time AC format), and by 1995, most of the remaining music programming was oldies-based; this made WHAS one of the last 50,000-watt clear-channel radio stations to feature music programming on a regular basis. Recent history Today the station features The Clay Travis and Buck Sexton Show, The Mark Levin Show (delayed by 2 hours), the last two hours of the national broadcast of Ground Zero, and Coast to Coast AM (live) on its daily lineup. Some other personalities on the weekday lineup have included Terry Meiners on "The Terry Meiners Show" and Lachlan McLean on "SportsTalk 840". The late morning slot (9 a.m. to noon) has seen two changes in recent years. Francene Cucinello hosted "The Francene Show" until her death on January 15, 2010; she was replaced that summer by Mandy Connell. In turn, Connell left in August 2013 to become the morning
