Watching a lot of old game shows during my staycation furlough, and have taken notice of a few shows that used manual spotlights that were for introductions and whatnot.
-- MGHSH for the celeb intros.
-- Classic Concentration for the cars and Alex's entrance.
-- TTTT '90 for the intros.
One common thread here is that these 3 shows came from NBC Burbank and likely from the Carson studio where the spotlights were already installed.
What other game shows regularly employed manually-operated spots? Obviously, I'm not including modern shows, like Millionaire, that have synchronized lighting displays.
