The National Broadcasting Company (NBC) is the oldest major broadcast network in the United States, founded in 1926 by the Radio Corporation of America (RCA), a subsidiary of General Electric (GE) at the time. Originally established as a pioneering radio network, NBC was the first permanent full-service national radio network in the U.S., beginning with a landmark four-hour broadcast that reached 2.5 million homes and subsequently producing the first coast-to-coast radio broadcast with the 1927 Rose Bowl game[1][3][4]. NBC played a key role in the development of broadcast media, transitioning from radio to television. It demonstrated television technology publicly at the 1939 New York World’s Fair and launched its first commercial TV station license in 1941. The network introduced innovations such as the first televised World Series (1947), the first color television program (1953), and iconic shows including *The Tonight Show* (1954) and *Saturday Night Live* (1975). NBC's signature three-chime audio logo, first used in radio, became a trademarked sound symbolic of the network’s identity[1][3][4][6]. Historically, NBC operated two radio networks—NBC Red and NBC Blue—until regulatory actions forced RCA to divest the Blue network, which became the American Broadcasting Company (ABC) in the early 1940s[2]. In the 1980s, NBC struggled in ratings but recovered under strategic leadership to dominate TV ratings with popular sitcoms like *Cheers*, *The Cosby Show*, *Seinfeld*, and *Friends*, and dramas such as *Law & Order* and *ER*[6]. NBC expanded into cable television early, launching CNBC—focused on business news—and MSNBC in partnership with Microsoft, offering round-the-clock news programming to compete with CNN[1]. Today, NBC is part of NBCUniversal, owned by Comcast, continuing to build on its legacy of innovation in broadcast and cable media,
