KTTV also airs reruns of "I Love Lucy", which had premiered in 1951, months after the station lost its CBS affiliation. Reruns of the sitcom are still popular among Southern California viewers and have continued to air in the Los Angeles market perpetually since the series ended its run in 1957, thus making KTTV only the second station in the market (the other being KCBS-TV) to continue airing the sitcom since it ended. Weekday airings of "I Love Lucy" have since moved to KCOP (which airs the program in a one-hour block), but KTTV continues to air the landmark sitcom on weekends during the late afternoon hours.
