The Smothers Brothers were haunted by the censors -- revisionist history is a dangerous thing, children. Do your research with primary sources. It's convenient for many to forget how dire those times were (unless, of course, they LIKED it that way), people blacklisted for opposing the war in Viet Nam on even the mildest basis (ask Eartha Kitt), FBI monitoring of everyone from John Lennon to Groucho Marx...Bill Paley and CBS were masters of censorship and dead thinking...the only reasons the Smothers Brothers lasted as long as they did was because they brought in money, they gave an edge to a prehistoric network that subsisted on Hee Haw and the Beverly Hillbillies. But Washington made its ugly voice heard, and that was that. If the times have changed, I'll be dipped if I can see it. The only reason All In The Family and Maude took off on that network is because of the almighty dollar -- the viewers made their voices heard, and viewer voices translate into dollars. The public has the responsibility and the power to change even the mightiest morons...don't forget that.
Also, never forget, the Nazis only lost ONE war!
