The same thing happened to Jobs when he revolutionized the music industry with ala carte music tracks via digital downloads on iTunes.
What Apple did with music isn't really relevant because it's a totally different business model than TV. Apple was/is just another middle man selling an end product (music) to consumers. What happened with music was a natural evolution. Music used to be sold to consumers on records, then 8-track, then cassette, then CD and then as downloadable digital files. Medium changed but the business model remained basically unchanged.
TV is a completely different ball of wax. TV shows are not end products sold to consumers. Consumers/TV viewers are the product and they are sold to advertisers. Been that way since the 1930s and currently ad revenue for OTA and cable/sat is somewhere in the neighborhood of 65-70 billion dollars annually. Considering things like the current business model has been used since the dawn of TV, the number of players in the game (untold number of production companies, broadcast networks, sports leagues, local TV stations, cable providers, sat providers, retailers, etc.,.) and the massive amount of ad revenue generated (which apparently these companies are all just supposed to turn their back on and 'assume' that direct sales will generate substantially more revenue) I'd say the industry as a whole is moving at a pretty decent clip towards change. I mean, in about 10 years we've basically gone from no-streaming options to cord cutting being pretty viable. Not to mention waiting for technology to improve. I mean, even if the TV industry was ready to go 'all in' 10 years ago there's no way the Internet at the time could have supported it.
If you want per-show a la carte then buy shows from Amazon or iTunes. I was a cord cutter for 5 years and that's how I kept up with SoA, Justified, Orphan Black, Walking Dead, The Americans, Breaking Bad, Dexter, etc.,
