69. 'The Ed Sullivan Show'
The Ed Sullivan Show aired live on Sunday nights as America's big showbiz variety fest, presided over by a granite-faced host who didn't look more than a century or two old. Sullivan gave the Beatles their big U.S. debut, breaking ratings records in 1964 when 73 million Americans tuned in to see the moptops do "She Loves You." He was also the guy who censored Elvis from the waist down and ordered the Stones to change "Let's spend the night together" to "Let's spend some time together," which may help explain why he finally went off the air in 1971.
