Not to worry. The CB frequencies are more or less useless for the technologies that seek radio spectrum for things like broadband internet. It's the higher frequencies that are coveted.
Over the air television has moved to digital transmission. In the same airwave space that a single TV channel used to occupy, a broadcaster can transmit multiple video channels and data services. It is simply better use of bandwidth.
