Sad to read about the passing of Grant Tinker, who along with then-wife Mary Tyler Moore created one of the most successful television production companies in history. MTM Enterprises was responsible for Moore's namesake show, as well as spinoffs "Rhoda," "Phyllis" and "The Lou Grant Show," as well as '70s classics "The Bob Newhart Show," "WKRP in Cincinnati" and "Hill Street Blues" He later was tapped to run last-place NBC, stunning everyone by turning it into the No. 1 network with "The Cosby Show," "Family Ties," "Cheers," "The Golden Girls" and "Miami Vice." Although he and Moore divorced in 1981, they remained close friends. Every night before I go to bed I watch a little Mary and Bob, which I still believe are the two best sitcoms of all time. RIP.
