NBC

The National Broadcasting Company (NBC) is an American English-language commercial broadcast television and radio network which is owned by Comcast through NBCUniversal. The network is headquartered at 30 Rockefeller Plaza in New York City, with additional major offices near Los Angeles, and Chicago. Along with ABC and CBS, NBC is one of the traditional "Big Three" American 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; it became a part of the network's official emblem in 1979 before being modified to its current form in 1986.
