In the early years of TTTT, the team of challengers sat on the left side of the set-to the host's right, while the celebrity panelists were on the right side. At what point did the TTTT stage layout change?

One day I happened upon UTUBE and found old shows. I spent a couple hours watching the shows. Just type in the name of the show and give your eyes a workout.

I think the panel on TTTT changed position some time in the 60s with Bud Collyer as host.
