Three shows from the 1970s generated an insane amount of spin-offs: All in the Family, Happy Days and The Mary Tyler Moore Show. Charting out the endless web they spun would require a PowerPoint presentation and a few very confusing hours. Somewhere in there would be Maude, who we first met in a 1971 episode of All in the Family where she played Archie Bunker's cousin. She's as liberal as he is conservative, and the show tackled many hot button political issues, most famously abortion. Bea Arthur played Maude for six seasons, and seven years after it ended she began work on Golden Girls, which had its own share of spin-offs.
