was reduced to three hours, every other Monday. The station's frequency was switched from Channel 1 to Channel 2 in March 1946 when the FCC decided to reserve Channel 1 for low-power community television stations, before eliminating it completely. The station was granted a commercial license (the second in California, behind KTLA) as KM2XBD, but calling it KTSL, on May 6, 1948 (and officially changed the call sign to KTSL on October 9, 1950), and was named for Thomas S. Lee, the son of Don Lee. The station became affiliated with the DuMont Television Network later that year. KTSL also launched Peter Potter's Jukebox Jury that year, a musical/quiz series that began to be broadcast nationally during the 1953–1954 season on ABC. Many later well-known entertainers appeared on the program to judge the latest releases from the recording companies. CBS acquisition (1949–1984) Starting in 1949, CBS had been affiliated with KTTV (channel 11, now a Fox owned-and-operated station), a station in which the network held a 49% minority ownership stake. Don Lee's broadcasting interests were placed for sale in 1950 following the death of Thomas S. Lee. General Tire and Rubber agreed to purchase all of Don Lee's stations, the centerpiece being KHJ radio, but chose to spin-off KTSL to CBS. Subsequently, CBS sold its share in KTTV to the station's majority partner, the Los Angeles Times, and all CBS programming moved to KTSL on January 1, 1951. On October 28, 1951, KTSL changed its callsign to KNXT (presumably meaning "KNX Television") to coincide with CBS' Los Angeles radio outlet, KNX (1070 AM). The station also moved its transmitter from Mount Lee, where it had been based since its experimental days, to Mount Wilson. As KCBS-TV (1984–present) On April 2, 1984, at noon, KNXT changed its call letters to the present KCBS-TV. The former KNXT call letters were later used by an unrelated TV station (now KIFR) in Fresno from 1986 to 2021. In 1997, it adopted the "CBS2" moniker for its on-air image, following the lead of sister stations WBBM-TV in Chicago and WCBS-TV in New York City. For a time during the 1980s and 1990s, KNXT/KCBS-TV had several locally produced programs such as 2 on the Town, a local show similar to Evening Magazine and KABC-TV's Eye on L.A., and KidQuiz, a Saturday morning children's game show hosted by longtime weathercaster Maclovio Perez (for a time in the
