This curiosity was born in the seventies. It was when TV stars were connected with their home network. ABC, CBS, and NBC would all send stars to compete with each other. I will admit it was fun to watch. You would see Telly Savalas, Lynda Carter, Kristy McNichol (remember her?) compete with each other with no other than Howard Cossell announcing.
Regular events included swimming, kayaking, volleyball, golf, tennis, bowling (on custom-made outdoor lanes), cycling, 3-on-3 football, the baseball dunk, running, and the obstacle course. As a pre-teen boy, I still remember Kristy McNichol was great on the obstacle course.
TV now is so fragmented that it would not work. They did try to bring it back in 2017 but it wasn’t the same and fewer viewers viewed with every episode. The networks didn’t want to share their actors with rivals. All of the contestants were from the Disney owned networks or older casts from long ago shows.
The original show ran from 1976 to 1988… Some of the Contestants are below the video.
