Hugo(Originally Danish I believe).. We used to have this TV-game in Finland where you could call to the live tv show with telephone(nope, not mobile one) and then used the buttons on phone to play several hugo games in realtime, sort of. I think it was kind of cool show and back then I thought it was so high-tech. I also tried to play the Tv-game but i never got in because of so many callers, and only few players were picked to play. >:
According to wikipedia it aired in 1993-1995.
