How many people have “been on TV”

How many people in the US have “been on tv”. There Isaacs got in my hometown who’s whole identity is that he was a contestant on a committe cooking show. I’m trying to gauge how common it is for a random person that you might meet at a bar to have been on TV. By this I mean:

• non actors
• not the news -not just in the audience

I think that predominantly leaves game show contestants and reality tv show contestants. What do you think?
