During the network era, which networks dominated?

• A. NBC, ABC, CBS
• B. FOX, NBC, ABC
• C. CBS, CNN, MTV
• D. PBS, ABC, FOX

Answer: (A)

During the network era, the dominant players were the three major broadcast networks that powered national programming. NBC, ABC, and CBS built wide national reach through affiliate stations, coordinating primetime schedules, news, and popular series. That network model attracted the bulk of national advertising revenue, enabling these networks to fund high-budget productions and maintain consistent scheduling across the country. Cable channels and niche networks like CNN, MTV, or PBS existed, but they didn’t command the same nationwide dominance in primetime and advertising during most of this period. Fox would rise later and gain influence, but for most of the network era the big three—NBC, ABC, and CBS—were the key players.
