Don't know.
But who says you can only enjoy 'That 70's Show' if you were alive back then? Sure, during the first few seasons every other line was a reference to the 70s. But after a few seasons they stopped doing it as often and it became a show about people. (Yes, they are still in the seventies, wearing the clothes in their technicolor homes, but it's not noticeable.)
I was born in the mid-eighties and I like 'That 70s Show'.
