Perkins Miller, who launched WWE’s digital streaming network in February, has left the company to join the National Football League and serve as its chief digital officer.

The WWE has not yet announced a replacement for Miller.

Miller had spent the past two years overhauling WWE’s digital initiatives, which included launching a popular app, as well as building out the company’s YouTube presence and WWE Network, which offers subscribers original series and access to pay-per-views and a vast library of programming for $9.99 a month. WWE announced that it had signed up nearly 700,000 subscribers as of April 7. The venture has already turned a profit for WWE.

His departure comes as a surprise; he presented at WWE’s business summit in New Orleans the day before “WrestleMania 30,” offering up the company’s extensive expansion plans which involved growing WWE’s presence overseas through mobile platforms.

But with the WWE Network having launched, much of the heavy lifting to set up that venture is done.

And the timing of Miller’s departure comes as the NFL is launching a similar network this summer called NFL Now that will enable viewers to create channels around their favorite teams or players.

Miller joined WWE in 2012 as executive VP of global digital media.

His resume includes serving as chief operating officer of Universal Sports Network, formed by NBC Sports and InterMedia; head of digital media for NBC Olympics; and senior VP of NBC Sports, where he launched NBCSports.com and oversaw its first Internet stream of an NFL game.
