Something about that rounded-rectangle shape is evocative of the YouTube logo - perhaps I was primed towards that as one of the signs shown is advertising "TV's".
I'm fairly certain that the YouTube logo, especially the original one, is meant to symbolize a Cathode Ray Tube (CRT) TV like this one: https://spencertified.com/cdn/shop/collections/Sears-Solid-S... (random example from image search). In times of linear TV, you'd ask whether anything was on the tube when you were wondering whether you'd want to watch something.
