Bravo showed every episode in the mid-Nineties. They were awful.
Really? Must be why I've never heard anyone claiming they invented comedy, or whatever.
But were they controversial at all?
Fom their site:
The Smothers Brothers Comedy Hour Featuring Tom And Dick Smothers.
With satirical and humorous sketches about politics,
The Viet Nam War and The Nixon Administration...
The Smothers Brothers helped shape American
political humor in the 1960's.
As a result of their out spoken views about politics,
The Smothers Brothers Comedy Hour was canceled...
Harlan Ellison mentions that they had run-ins for (1) appearing full-frontal nude and (2) doing a sketch pointing up the hypocrisy in attitudes toward legal/illegal drugs. But it's 10 years since I read the book and I don't have a copy to check.
I'm sure he said though that they got replaced with a show called "What's It All About, World?" which tried to be a right-wing satire show, and actually had a pro-Nixon song and dance routine. I'm sure that's what I read, anyway.
