LORNE MICHAELS, 72
Creator/executive producer, Saturday Night Live; The Tonight Show Starring Jimmy Fallon
Last Year's Rank: 70
Michaels guided SNL through its most-watched season in 24 years with an average 10.8 million viewers per episode, and its musical performances -- which included The Weeknd, Lady Gaga and, in advance of their Grammy nominations, Chance the Rapper and Sturgill Simpson -- remain an offer that no artist can refuse. In primetime, Greenblatt added Simon Cowell to the judges' panel on America's Got Talent, which helped the show notch its most-watched season in five years. His experience as a Broadway producer also informs NBC's continuing programming of live TV musicals. Bye, Bye Birdie, starring Jennifer Lopez, is slated for December.
Prized Music Memorabilia: Greenblatt: "The original conductor's scores to the movie musicals Singin' in the Rain and An American in Paris."
