 The station was initially affiliated with ABC.In the early 2000s, ABC asked for its affiliation with KNTV to end, so that its owned-and-operated KGO-TV could serve the South Bay portion of the Bay Area (and reap the local advertising revenues); after a very brief series of affiliation and ownership changes, KNTV became owned and operated by NBC, which lost its longtime affiliate KRON-TV after a dispute with new ownership.The KNTV transmitter tower is now located on San Bruno Mountain.
