 On November 5, 1949, CPC would sign on KRON-TV on VHF channel 4, which became the National Broadcasting Company (NBC) affiliate for the San Francisco Bay Area television market.This was much to the chagrin of NBC itself, which was a runner-up for the station and would desire KRON for the next half-century.In the 1950s, KRON would add an FM radio station (KRON-FM, now under call sign KOIT) at 96.5 MHz.
