UNDATED (AP) - It was 50 years ago today that the Beatles appeared on "The Ed Sullivan Show."
Their first appearance in America was a pivotal cultural moment.
Nielsen says 45 percent of all TV sets in use at the time were tuned into the broadcast, or more than 70 million viewers. Some who watched were already fans, while others were just curious about the new phenomenon of "Beatlemania."
The Beatles performed live before an audience full of screaming teenage girls in the CBS studio in Manhattan that now houses the "Late Show With David Letterman."
