How many people watched the Apollo 11 moonwalk live on TV?
Answer
600 million
About 600 million people watched the Apollo 11 moonwalk live on television.
That figure is an estimate, not a precise headcount. Neil Armstrong’s first steps on the Moon were transmitted internationally on July 20–21, 1969, and reached roughly one-fifth of the world’s population. Television networks assembled a global broadcast using tracking stations, satellite links, and ground-based relay systems.
The audience estimate is often confused with the number who watched the launch or with later estimates that use different population and household assumptions. The 600-million figure specifically refers to Armstrong’s moonwalk broadcast and is the standard figure used in accounts of Apollo 11. It made the event one of the most-watched television broadcasts in history.
