In 1974, NBC "Tonight Show" host Johnny Carson asked that the weekend broadcasts of "Best of Carson" (officially known as "The Weekend Tonight Show Starring Johnny Carson") come to an end ("The Tonight Show" was a 90-minute program at the time), so he could take two weeknights off; NBC would thus air those repeats on those nights rather than feed them to affiliates for broadcast on either Saturdays or Sundays. Given Johnny Carson's undisputed status as the king of late-night television, NBC heard his request as an ultimatum, fearing he might use the issue as grounds to defect to either ABC or CBS. To fill the gap, the network drew up some ideas and brought in Dick Ebersol – a protégé of legendary ABC Sports president Roone Arledge – to develop a 90-minute late-night variety show. Dick Ebersol's first order of business was hiring a young Canadian producer named Lorne Michaels to be the show-runner.
