The network is part of the Big Three television networks. 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.It was home of the 2016 Rio Olympics as well as the Paralympics.

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 to General Electric (GE) – which previously owned RCA and NBC until 1930, when it was forced to sell the companies as a result of antitrust charges – through its $6.4 billion purchase of RCA. Following the acquisition by GE (which later liquidated RCA), Bob Wright served as chief executive officer of NBC, remaining 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 NBC Universal and was replaced as CEO by Comcast executive Steve Burke.
NBC has thirteen owned-and-operated stations and nearly 200 affiliates throughout the United States and its territories, some of which are also available in Canada via pay-television providers or in border areas over-the-air; NBC also maintains brand licensing agreements for international channels in South Korea and Germany.
