I don't recall this being discussed before...but I'm wondering about decisions over when shows used long credits (full credit roll), vs. short credits (usually just the production company, taping location and show title).
The original Hollywood Squares usually ran full credits after the Thursday show (Peter even mentioned on a couple of shows something like "...it's Thursday...be sure to watch the "crawl" (as he called it) to see all the great people that work in this show..."
A few weeks before its first birthday, Match Game 7x settled into almost always having its full roll on the fifth and last show with a particular panel (which didn't always air on a Friday).
There are other shows where I recall seeing full credits two or three times a week, and some others where sometimes you'd go a couple of weeks before you'd see it.
One that comes to mind: maybe I'm mis-remembering, but I seem to recall a stretch on The Price is Right in the summer of 1973 where they want almost three full weeks before the full roll was shown.
Was it just the case of a show running a minute short, so the director will say "let's run the full credit roll today"?
Any thoughts?
