Since a large number of sports teams exist within the San Francisco Bay Area and the rest of Northern California, NBC Sports Regional Networks maintains two owned-and-operated outlets which split coverage of local sports: NBC Sports California and NBC Sports Bay Area. It is the only market served by NBC Sports Regional Networks where two 24-hour, full-time NBC Sports affiliates operate. Due to the territorial rules set by the National Basketball Association, Golden State Warriors games do not air in the Sacramento–Stockton–Modesto television market on NBCS Bay Area, while for the same reason, NBCS California cannot air Sacramento Kings telecasts in the San Francisco–Oakland–San Jose market.
