The National Broadcasting Company didn’t start as a TV giant. It started as a radio experiment. In 1926, National Broadcasting Co. (NBC) was formed by RCA Corp., General Electric Co. (GE), and Westinghouse. It was the first U.S. company to operate a broadcast network. David Sarnoff, president of RCA, directed the early operations. By 1930, NBC was wholly owned by RCA.
Why NBC split into Blue and Red Networks
NBC initially divided its operations into two semi-independent networks. The Blue Network, based on station WJZ, and the Red Network, based on WEAF, each linked to stations in other cities. The Red Network carried 75% of NBC’s programs by 1938. The Blue Network struggled. In 1941, NBC sold the Blue Network. It became the American Broadcasting Co. (ABC).
The sale of the Blue Network in 1941 created ABC, leaving NBC with the stronger Red Network as its core.
Where NBC stood after entering television
NBC entered television broadcasting in a weakened position. By 1952, it trailed CBS in audience ratings. It gradually regained its leading position. The transition was not smooth.
Which corporate shifts defined NBC’s modern era
In 1986, RCA was sold to GE. In 1987, NBC sold its radio networks. The 1990s brought expansion into cable television. NBC created MSNBC in an alliance with Microsoft. It also created CNBC in an alliance with Dow Jones.
The history of NBC is a record of splits, sales, and strategic pivots. From radio dominance to cable expansion, the company has never operated in a single format. Its current structure reflects decades of divestitures and partnerships. The radio networks are gone. The cable arms remain. What comes next is still unfolding.
