It’s hardly a secret that the tenuous future of pay TV, and those $150+ monthly bills, relies almost entirely on live sports. That’s why Disney is happily forking over $2.6 billion a year for a package of NBA games that represents twice the cost and essentially half the content of its current deal. It’s also why WBD’s David Zaslav publicly kissed up to NBA commissioner Adam Silver at the Milken Conference yesterday—he needs to renew his company’s own TNT deal, also likely for more than twice the current price, especially after lingering negotiation talks left the door open for Comcast C.E.O. Brian Roberts to put a $2.5 billion per annum proposal on the table. My partner John Ourand reported yesterday that Amazon is set to pay $1.8 billion per year for a third package—a harbinger that the streamers will only redouble their efforts to yank live sports rights from the maws of legacy mediacos in the future.
