Streaming TV has gotten popular as several online services such as Netflix make past seasons of TV shows available for binge-watching, while Hulu offers episodes from the current season. Making streaming TV too pleasant might encourage viewers to cut back or drop their cable service. In turn, TV production companies make a lot from licensing fees paid by the networks. The Wall Street Journal recently reported that Time Warner is in talks to invest in Hulu and has told Hulu's owners that it wants to curtail current-season TV episodes, which Hulu now makes available as early as the next day. The tremors emanating from Time Warner are just the latest instance of established media companies looking to protect their established partners and deals, whether viewers like it or not. The changes are especially noticeable at Hulu, which is owned by parents of the very television networks — Fox, ABC and NBC — threatened by changes in the way we watch TV. The apparent anxiety at television companies is common to any industry that's faced what Harvard business professor Clayton Christensen calls "The Innovator's Dilemma." The fees that cable and satellite companies pay television networks and stations to carry their channels are estimated at $60 billion this year, up 6 percent from 2015, according to media research firm SNL Kagan.
