’80s, where actors and writers learned to create sitcoms and then moved on and created other shows: the MTM school, which begat Taxi, Frasier, Cheers, Wings, and Family Ties, and the Garry Marshall school, which begat The Odd Couple, Happy Days, Laverne & Shirley, and Mork & Mindy. To be MTM-pedigreed in those years was a seal of approval. You still had to prove yourself, but it helped you get in the door. There was also a shorthand between people who worked together on similar projects.
