what year(s) was the show ONE ON ONE taken?

Answer 1

Go to IMDb.com.
I checked it out and there are several with that title from different years. Unfortunately none of them had much info, in fact, there's one from 2000 that only shows 2 people in the cast and then it looks like they tried again in 2001.
There was also a show in 1984 and 1974(?).

Good luck!
