In 1976, channel 4 became the second station to adopt Dick Marx's "WBBM Channel 2 News Theme", that eventually became the de facto official newscast music for CBS' owned-and-operated stations. The theme was dropped by the station in 1986 after Viacom took control, though from 2001 to 2008, the station used the Frank Gari-composed "CBS Enforcer Music Collection", which uses a music signature derived from the WBBM package. Ironically from 1989 to 1992, KMOV used Gari's "News Series 2000", which was traditionally associated with ABC stations, as its news theme. In July 2018, the "CBS Enforcer Music Collection" theme returned to the station, replacing their previous theme, the Gari-composed "The Edge."
