I would call him a celebrity. I've never really followed baseball and always knew who he was. From the early 80s to the mid-00s, was a bit of a household name, whether the household was into baseball or not, thanks to his big personality, his sponsorships and a lot of cameos playing himself in pop culture. Wikipedia lists the shows "Silver Spoons, Who's the Boss?, CHiPs, Hart to Hart, Fantasy Island, Hee Haw, Simon & Simon, Everybody Loves Raymond and American Restoration" and he was on lots more if you look at his imdb.com entry.
