On what American television show did the Beatles famously appear in 1964 with approximately 73 million viewers?

Ed Sullivan happened to pass by the Beatles being greeted by their fans at Heathrow airport in London and acting on a gut feeling, asked the Beatles to appear on one show at top dollar. Their manager asked for three shows at bottom dollar with top billing, just for the exposure. They never appeared again after the first show however, as their career skyrocketed and they no longer needed the publicity.
