When I was kid, there was a local tv station in NYC called 'WPIX 11', channel 11 obv.
They had a segment that aired during commercial breaks, where they picked a caller, and put them on the air, and they got to play an Intellivision game. There was football, and some space shooty type game. You didnt get to pick which one you played.
The way you played on the phone was you yelled 'PIX' and your gun would shoot, or your quarterback would throw a pass. I didnt realize this as a little kid, but all this was, was someone in the tv studio playing the game on the Intellivision and simply pushing the button whenever the caller yelled 'PIX!'.
If you completed enough passes, or killed enough alien ships, then you won a prize.
This segment led to two main playing strategies from the callers. They would either try to time their shots like "...........PIX!..............PIX!...." or they would go crazy and yell as fast as they could "PIXPIXPIXPIXPIXPIXPIX!" until they ran out of breath. You got to play for 30 seconds, and I think the entire segment was one minute long.
