Recent efforts like the Amazon Original Series "The Man in the High Castle" (based on the Philip K Dick book of the same name) show that the future of TV should be companies making programming based on what people want to watch (and are willing to pay for) rather than on what the companies convince advertisers to support.
But as long as dinosaur last-century media companies like Comcast, Time Warner, CBS corporation, Fox, Disney, Viacom and others continue to do everything they can to preserve their status as gatekeepers dictating what content people get to see, the future of TV will be people paying ever-increasing subscription fees for overpriced pay TV products that force them to pay for 500 channels they dont want just to get the 5 channels showing content they are actually interested in.
Disney is by far the worst offender here where they force anyone who wants ANY of the vast portfolio of Disney content (including rebroadcasts of their local ABC affiliate) has to pay money for ESPN even if they dont want it, dont like it and never watch sports at all. Should ESPN go away? No, plenty of people DO like what they air. But Disney should stop forcing ESPN (probably one of the more expensive channels when it comes to how much the TV companies pay to get it on their platform) on people who dont want it and will never watch it.
