It is a close contest between the History Channel and TLC. The winner would have to be TLC used to be fun and interesting and have really cool programs about science but when it made the switch to reality TV in an attempt to boast ratings most of the other networks followed.

Sure there are bad things about Discovery and History but Pawn Stars, Ax Men and Ice Road truckers would never have been a thing unless TLC proved it could be profitable. And as much as I hate History Channel programming 95% of the time at least they never pitched Toddlers and Tiaras as a concept.

Seriously anyone who pitched the concept of T&Ts never needs to be in charge of producing a television show ever again.
