Telegraph: David Zaslav, CEO of Discovery Networks, the television arm of John Malone’s global media and telecoms empire, has called on the industry to push back against erosion of its power by Apple, Amazon and Netflix. Zaslav said broadcasters and producers should resist pressure to serve up programming piecemeal to the benefit of technology giants. “Where’s Netflix without our great content? How many iPhones would you buy if all of our stuff wasn’t on there?”
