Just ask the network executives who tried to launch ABC's "Cop Rock," a 1990 series in which detectives turned the interrogation box into a karaoke bar, or "Smash," the 2012-13 NBC drama about a Marilyn Monroe musical that died out faster than a candle in the wind.
CW's "Crazy Ex-Girlfriend" won a Golden Globe for its madcap novelty numbers, but its final season last year only drew about a half-million viewers.
Now Hollywood is betting that audiences are ready to change their tune.
"I think people are looking for joy and hope in the world right now," veteran TV writer Austin Winsberg said back in January. "Musicals can touch upon deep emotions and can bring up stuff that's hard to say in words."
Winsberg is leading the chorus line with "Zoey's Extraordinary Playlist," his NBC dramedy about a crafty coder who imagines those around her as players in a never-ending series of Broadway numbers.
"Soundtrack," currently streaming on Netflix, features its looking-for-love characters lip-syncing to Whitney Houston and Joni Mitchell. On May 8, "La La Land" director Damien Chazelle will bring his love of musicals to the small screen for Netflix's "The Eddy," set in a Paris nightclub.
In the animated series "Central Park," debuting on Apple TV in late May, a family of park caretakers spends more time warbling original songs than picking up trash. Alicia Keys, the Chainsmokers and Billy Joel are also eyeing musical projects for TV.
"Musicals went out of style for so long," said Kristen Bell, who voices a character on "Central Park." "There's a way to do it in which it's just a story and you stop for a song, then more story and another song. It feels disjointed. You can tell that something's off. But when you're doing it right, the audience doesn't even know why they're so interested in it. You're tricking them."
