I am curious about the show in its format. I know the early years 76-81 were 30 minutes.
Then in 1981, it ran on NBC for two years (I think) under SCTV 90 (as in it was 90 minutes long). Then in 1983-84 season, its last I believe, ran for 45 minutes on Showtime cable network.
My question is, why so many formats?
Why didn't last longer than it did on NBC under the 90 minute format?
The DVDs of the shows, I thought of buying a couple off Amazon.com, do they include every from the particular shows or are there awkward edits?
