WWF
Seriously, I have no clue, the list is long.
ER
Law & Order
Friends
Night Court
Cosby Show
Mash
LA Law
TJ Hooker
Simpsons
OJ Trial
Clinton TV
Mod Squad
Dallas
Brady Bunch *[insert]shudder[/insert]*
The Price is Right
Saturday Night Live
Mad TV
The Tonight Show (Jay Leno, Carson and the other two guys)
The list just goes on and on and on and on and on.
But I would generally say that the top non scifi show would have to be one with a lot of hot chicks scamply clothed and running around on a beech.
