Apollo 11 Moon Landing
The Apollo 11 moon landing on July 20, 1969, is the most-watched television event in American history, with an estimated 125–150 million viewers across all networks. When Neil Armstrong stepped onto the lunar surface, more than 650 million people worldwide watched the broadcast. In the United States, all three major networks (ABC, CBS, NBC) interrupted their regular programming to provide continuous coverage. It was the first time humanity watched a live event from another world, and it remains the most culturally significant broadcast in television history.
