Long before streaming made it possible to watch an entire season in a weekend, Americans spent years checking in with the same television families one episode at a time. The sitcom mothers of the 1970s and 1980s ranged from traditional homemakers to lawyers, reporters, waitresses, musicians, divorcees, widows, and women who gleefully rejected practically every rule of respectable motherhood. Some offered comfort, some delivered tough love, and a few probably taught viewers exactly what not to do. Together, these memorable characters helped redefine what a TV mom could look like.
