I have a friend who is a free-lance video engineer for many sporting events.
He recently posted a photo to his FB page, showing (IIRC) TWENTY-SEVEN remote control units lined up on his console. Several were actually on an (I swear I'm not making this up)....actual "TV Tray". One of those folding things we used to eat TV Dinners off of, while watching the Captain, Mr GreenJeans, and Mister Moose.
I think that was "merely" a baseball game....not even close to Super Bowl.
