NBC

The National Broadcasting Company (NBC) is an American commercial broadcast television and radio network that is the flagship property of NBCUniversal, a subsidiary of Comcast. The network is headquartered in the Comcast Building (formerly known as the GE Building) at Rockefeller Center in New York City, with additional major offices near Los Angeles (at Universal City Plaza) and in Chicago (at the NBC Tower). NBC is sometimes referred to as the "Peacock Network", in reference to its stylized peacock logo, which was originally created in 1956 for its then-new color broadcasts and became the network's official emblem in 1979.
