What is the Number One Watched TV Show Ever?

Published in Television History 2 mins read

While the term 'TV show' typically refers to a regular series, the most-watched television broadcast event of all time is widely considered to be the Apollo 11 moon landing on July 20, 1969.

This monumental event captured the attention of a global audience, with reports indicating that an astounding 125 to 150 million people tuned in to witness humanity's first steps on the moon. This figure places it as an unparalleled moment in broadcasting history due to its widespread and simultaneous viewership.

It is important to understand the context of historical viewership data:

  • Reported Viewership: The widely cited figure of 125–150 million viewers represents a massive global reach for the live broadcast.
  • Nielsen Substantiation: While these numbers are widely reported, Nielsen Media Research, the primary authority for television ratings, has historically published only household viewership figures for the Apollo 11 landing. They have not fully substantiated individual viewer counts within the 125–150 million range, as their methodologies for tracking audiences were different at the time.
  • Evolving Measurement: The methods for tracking television viewership have evolved significantly since 1969. Early measurements often focused on households, and comprehensive individual viewer data was more challenging to collect and verify, especially for global events.

The Apollo 11 moon landing stands as a unique broadcast, transcending typical entertainment programming to become a unifying, global experience watched by an unprecedented number of people.
