With rare material from the Entertainment Tonight vaults, a prime-time special pays homage to the great TV producer Norman Lear, who passed away this week at 101. His groundbreaking comedies on CBS (All in the Family, Maude, The Jeffersons, Good Times, One Day at a Time) and NBC (Sanford and Son) changed the face and possibilities of TV by injecting social commentary and satire into the sitcom format. Nischelle Turner hosts the hourlong tribute, with appearances by Jimmie Walker (Good Times) and Mackenzie Phillips (the original One Day at a Time) and excerpts from an in-depth interview conducted by Kevin Frazier to mark Lear’s 100^th birthday. Also of note, Catchy Comedy presents The 200^th Episode Celebration of All in the Family (8/7c), a replay of a 90-minute retrospective special of Lear’s greatest, most groundbreaking series. (MeTV will show it Sunday at 6/5c.)
