from wikipedia:

Maude is a half-hour American television sitcom that was originally broadcast on the CBS network from September 12, 1972 until April 22, 1978.

"Maude starred Beatrice Arthur as Maude Findlay, an outspoken, middle-aged, politically liberal woman living in suburban Tuckahoe, Westchester County, New York with her fourth husband. Maude embraced the tenets of women's liberation, always voted for Democratic Party candidates, strongly supported legal abortion, and advocated for civil rights and racial and gender equality. However, her overbearing and sometimes domineering personality often got her into trouble when speaking out on these issues.

The program was a spin-off of All in the Family, on which Beatrice Arthur had first played the character of Maude, Edith Bunker's cousin; like All in the Family, Maude was a sitcom with topical story lines created by producer Norman Lear."

Such a show would never make it on the air nowadays...

Also, big bosoms like Barbeau's aren't allowed on TV either:
