The reason this won’t work is that most of the cable stations are owned by the networks. They require you buy all of their channels or none.
So if you choose not to get ABC, you won’t get any ESPN or Disney.
Don’t want F/X? Then you lose FoxNews, etc.
The important part is if they dont offer free airway service that bandwidth is available again and some local broadcaster can pick it up. Also there will no longer be restriction on sporting events. Your local town/city can show any Sports game that built the stadium or coliseum.
ala carte will not allow cable companies to package it. The law would force a channel per channel charge.
