During his talk, Dodge also slammed TV broadcasters and the legal system that governs how cable and satellite providers must negotiate for the rights to carry local TV networks.
"That's a system that should be destroyed now," Dodge said. "It's not a fair fight and ultimately consumers are the ones in the crosshairs."
He argued that cable and satellite providers should be allowed to carry out-of-market TV channels if the local network insists on blacking out when negotiations break down. Broadcasters say that change would undermine their ability to get a fair price for their content.
