There was a show called "You can't do that on Television" back in the (19)80's on Nickelodeon. Sometimes they'd ask the home audience to participate and 'vote' by pressing a Red or Green square on the screen. Although I always wondered how it worked, I really believed my vote went through by touching the TV screen. & sometimes, when I thought I was being slick, I wouldn't vote, just to see if 'they' would notice and say something to me on TV or send a letter to my mom.
