As you will note, currently the best shows on "television" are developed by HBO, and Netflix, both subsription based providers. Cable is going to continue a downward trend as more people flock to the internet based providers, especially with the new generation of smart tv's, playstation/xbox, etc. The old behemoths of entertain need to get on the bandwagon as soon as possible, otherwise they are going to hermorage marketshare. Subscription based consumption is a great model, and will continue to grow. Advertising based shows will also be around, and we already see it moving to the web more and more each day. TV shows will always be around, its just that the traditional cable TV is what is dying, there will always be a steady stream of content suppliers.
