Rob Mills, ABC's head of alternative series, specials and late-night programming, explains why the network embraced "the show must go on" mantra to salvage "American Idol's" live performance episodes amid the coronavirus shutdown. Mills also discusses the return of "Who Wants to Be a Millionaire" with Jimmy Kimmel, his desire to get "The Bachelor" back in production as soon as possible and why the economics of game shows make them so attractive to networks.
