Welcome to the new cable industry. All your local affiliates are bought up by companies that want to make money off you and your cable provider. Then your cable provider, who do try and negotiate for your well being (I've been through this through a third party vendor for a cable company, so I have first hand experience), is unwilling to take all of those costs on, so your bill goes up.
It's greedy versus greedy and we're in the middle. The only real way to stop it is to get rid of all the affiliates and have one CBS, one NBC, etc. for everyone.
