In the few areas of the western United States where an NBC station is not receivable over-the-air, KNBC is available on satellite television through DirecTV.
History
Channel 4 first went on the air as KNBH (standing for "NBC Hollywood") on January 16, 1949. It was the penultimate VHF station in Los Angeles to debut, and the last of NBC's five original owned-and-operated stations to sign on. Unlike the other four, KNBH was the only NBC-owned television station that did not benefit from having a sister radio station. The NBC Radio Network had long been affiliated with KFI in Los Angeles, though that relationship did not extend into television in August 1948 when KFI-TV (channel 9, now KCAL-TV) signed on the air. When KNBH signed on, it marked the debut of NBC programs on the West Coast.
