UPN continued to broadcast on stations across the country until September 15, 2006.
While some of the network's affiliates that switched to My Network TV (which commenced operations on September 5, 2006) aired the final two weeks of UPN programs outside of its recommended primetime slot, the Fox-owned stations, including KCOP, dropped UPN entirely on August 31, 2006.
Operating as an independent station early on, it began running some programming from the Du Mont Television Network in 1949 after KTLA (channel 5) disaffiliated from the network after a one-year tenure.
The KMTR call letters are currently used by NBC affiliate in Eugene, Oregon. On December 23, 1953, the Copley Press (publishers of the San Diego Union-Tribune) purchased KLAC-TV and changed its call letters to the current KCOP.Channel 13 was the last local television station to air cartoons on weekdays; like the other local stations, the cartoons were replaced with informercials.In a separate transaction from its purchase of UPN, Viacom purchased KCOP's rival, KCAL-TV, from Young Broadcasting on June 1, 2002.KCOP was the original Los Angeles home of the syndicated versions of Wheel of Fortune (its longtime announcer until his death in 2010, Charlie O'Donnell, was a former news anchor at KCOP) and Jeopardy!
, both of which moved to KCBS-TV (channel 2) in 1989, and later to KABC-TV (channel 7) in 1992.For most of its first 46 years on the air, channel 13 was a typical general entertainment independent station.
