WNBC, channel 4, is the flagship station of the NBC television network, located in New York City. WNBC's studios are co-located with NBC corporate headquarters at 30 Rockefeller Plaza in midtown Manhattan. WNBC is the sister station to Linden, New Jersey-based WNJU (channel 47, flagship of the co-owned Telemundo network), and the two stations have some cross promotion.

In the few areas of the eastern United States where viewers cannot receive NBC programs over-the-air, WNBC is available on satellite via C band, and to subscribers of Dish Network and DirecTV, which also provides coverage of the station to Latin America, the Caribbean, and Jetblue's LiveTV inflight entertainment system.
