Camera Crews and the Diamond Vision

Firstly, they need a second screen on the opposite side of the field.

Secondly, and for my real topic: What happened to the days when unknowing fans would regularly be featured on the diamond vision during stoppages in play? Did too many ppl 'finger' the camera, or mouth the words "F*** YOU!!"? Maybe they sold too much advertising space?! That may be a way to get the fans into the game more, show some wild fans on the jumbo screen.
