At its start, RCA was the largest radio communications company in America. It not only manufactured radio equipment but also controlled the nation’s first network of radio broadcasters, known as the National Broadcasting Corporation, or NBC. At the time of the creation of RCA, David Sarnoff was American Marconi’s “commercial manager.” He would come to have the same job at RCA and play a pivotal role in its future, eventually rising to become the president of RCA. He was also the founder of NBC.
