AT&T’s Christopher Talks Streaming

AT&T recently completed its $85 billion purchase of Time Warner, a deal designed to help traditional media companies compete better with nimble tech services such as Netflix. Soon after the deal closed, AT&T launched WatchTV, a $15-a-month streaming service that offers more than 30 TV channels, including Time Warner channels TNT and TBS. David Christopher, who runs AT&T’s wireless and entertainment businesses, talks about how people are consuming media and what role wireless companies play.
