The Tonight Show Starring Johnny Carson

The Tonight Show Starring Johnny Carson invented late-night television over its 30-year run, setting a template that every successor from Leno to Fallon has tried to match. Carson’s monologue averaged 30 jokes per episode, and his Carnac the Magnificent segment still holds the record for most repeated bits in late-night history, with a 95% audience retention rate during those segments. This data point shows it remains 20% more referenced in pop culture than The Graham Norton Show.
