Question: I recently saw a documentary on the TV series Cheers. I was wondering, what other series besides Cheers and M*A*S*H lasted longer than 10 years? Thanks. — Joan, Kawasaki, Japan

Televisionary: A lot more than you think, Joan. It's too long a list to run here in its entirety, but I can give you highlights. Gunsmoke was the longest-running drama or comedy (20 seasons), followed by such shows as: Lassie (17); The Simpsons (15); The Adventures of Ozzie & Harriet, Bonanza, Dallas, Knots Landing, Law & Order (14); various incarnations of All in the Family and The Danny Thomas Show (13); Hawaii Five-O, Murder She Wrote, My Three Sons (12); Happy Days, The Jeffersons, Married... with Children, NYPD Blue (11)....

You get the picture.
