The National Broadcasting Company (NBC) is an American English-language commercial terrestrial television network that is a flagship property of NBCUniversal, a subsidiary of Comcast. The network is one of the Big Three television networks. NBC is sometimes referred to as the "Peacock Network", in reference to its stylized peacock logo, introduced in 1956 to promote the company's innovations in early color broadcasting.

Founded in 1926 by the Radio Corporation of America (RCA), NBC is the oldest major broadcast network in the United States. In 1986, control of NBC passed back to General Electric, 50 years after being separated due to anti-trust charges. In 2003, French media company Vivendi merged its entertainment assets with GE, forming NBC Universal. Comcast purchased a controlling interest in the company in 2011, and acquired General Electric's remaining stake in 2013.

NBC has thirteen owned-and-operated stations and nearly 200 affiliates throughout the United States and its territories.
