Who served as general manager of RCA and helped create NBC?

• A. David Sarnoff
• B. Fred Silverman
• C. Christiaan Huygens
• D. D. W. Griffith

Answer: (A)

The main idea here is identifying the leader who built RCA into a major broadcasting force and helped launch NBC as a national network. David Sarnoff rose to the top at RCA and steered its strategy during radio’s rise to mass medium status. In 1926, under RCA’s umbrella, NBC was created to coordinate and distribute programming across the country, making Sarnoff a central figure in establishing a nationwide broadcast network. His influence extended into television as RCA and NBC evolved with new technologies, cementing his role in shaping American broadcasting.

The other names come from different times or fields: Fred Silverman is a later television executive, while Christiaan Huygens was a 17th‑century scientist and D. W. Griffith a pioneering silent-film director.
