National Broadcasting Company

The National Broadcasting Company (NBC) is an American English-language commercial broadcast television and radio network owned by Comcast. The network is headquartered at 30 Rockefeller Plaza in New York City, with additional major offices near Los Angeles (at 10 Universal City Plaza), and Chicago (at the NBC Tower). NBC is one of the Big Three television networks, and 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 the network's official emblem in 1979.<p>

Founded in 1926 by the Radio Corporation of America (RCA), NBC is the oldest major broadcast network in the United States. At that time, the parent company of RCA was General Electric (GE). In 1932, GE was forced to sell RCA and NBC as a result of antitrust charges. In 1986, control of NBC passed back to General Electric (GE) through its $6.4 billion purchase of RCA. GE immediately began to liquidate RCA's various divisions, but retained NBC. After the acquisition by GE, Bob Wright became chief executive officer of NBC; he would remain in that position until his retirement in 2007, when he was succeeded by Jeff Zucker.

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. Following the Comcast merger, Zucker left NBCUniversal and was replaced as CEO by Comcast executive Steve Burke.
