AT&T CEO said Wednesday his company's tie-up with DirecTV is helping it combine its wireless and video businesses.
"Being really early, six months into it, I would tell you we're more enthusiastic today than we were when we first started it," he told CNBC's "Squawk Box" at the World Economic Forum in Davos, Switzerland.
AT&T recently announced it would reinstate unlimited data for customers who subscribe to its U-Verse television plans or DirecTV's satellite TV service. AT&T closed its deal to purchase DirecTV for $49 billion in July.
To support the new unlimited plans, AT&T will bring a large block of spectrum to market that currently hosts no traffic, Stephenson said. He said AT&T is in a unique position thanks to its portfolio of infrastructure — including satellite, fiber optics and wireless — to deliver data.
AT&T was able to offer unlimited data — a proposition that other carriers have dropped or limited — because it began building up its portfolio of spectrum needed to carry that data years ago in anticipation of its current strategy.
"The bet we made ... was TV everywhere is going to be very, very important," he said. "People have been pursuing TV everywhere for a long time. I don't think anybody has really executed on it very well."
He said Netflix has so far done the best in allowing customers to watch video anywhere and anytime, offering customers a "nice user interface" across devices.
"This is what we're after. Our content agreements are the long pole in the tent for getting this to market," he said. "We're getting those content agreements done very quickly."
