NEW YORK (AP) -- Grant Tinker, who brought "The Mary Tyler Moore Show" and other hits to the screen as a producer and a network boss, has died.
Tinker died Monday at his home in Los Angeles, according to his son, Mark Tinker. He was 90.
Though he spent years at NBC, Tinker is best known for his work at MTM Enterprises. He founded the company in 1970 with then-wife Mary Tyler Moore. In addition to Moore's own groundbreaking situation comedy, MTM scored with series' including "Rhoda," ''The Bob Newhart Show" and "Hill Street Blues."
Tinker became NBC chairman in 1981 and led the network out of the cellar with hits such as "The Cosby Show" and "Cheers."
