KNSD is the NBC affiliate for the San Diego, California market, broadcasting on digital channel 40, displayed as virtual 39. It has a subcarrier: 40.2, that broadcasts Cozi-TV (classic television programs).
Channel 39 first signed on in 1965 as independent KAAR, the city's first UHF station. A lack of adequate programming and extremely low budgets in 1966 closed down the station till 1968 when it went back up as KCST. It remained an independent until in 1972 KCST filed a petition against then-ABC affiliate XETV/channel 6. XETV was licensed to Tijuana, Mexico while serving San Diego proper, and KCST charged that a station licensed to another country could not be affiliated with an American television network. KCST successfully won the ABC affiliation and the change, with XETV reverting to independent status, took place in stages. Two ABC daytime shows that XETV did not clear landed on KCST in April of 1973, the rest of the ABC daytime schedule landed on KCST a month later, and the rest of the ABC line-up moved there on July 1, 1973. ABC was not happy with landing on a UHF station and in 1977 changed to KGTV/channel 10, which then was an NBC affiliate. NBC would conversely land on KCST.
The station changed calls to the current KNSD in 1988. Their branding of 7 is denoted from their channel position on all San Diego cable systems, which is channel 7. Previously they were known as "7/39," denoting their cable position and their virtual channel number (old analog position), which is 39. Their syndicated programmimg is hubbed from KNBC/channel 4 in Los Angeles, and their morning news has an outdoor setting at their studios on Broadway in downtown San Diego. KNBC is also the origination for KNSD's weather forecasts segments. The station produced a 10 PM newscast for KSWB/channel 69. Upon their switch to Fox, KSWB's newscast became in-house produced.
