ATT has officially unveiled its DirecTV Now internet TV streaming service, which launches Wednesday, November 30th, in the U.S. on iPhone, Android, Amazon Fire TV, Chromecast, and PC/Mac, starting at $35 per month. The Verge reports: Like its over-the-top rivals, DirecTV Now will let customers stream live programming on smartphones, tablets, and PCs -- no cable box necessary -- and requires no long-term contracts or commitments. For a limited time, ATT will offer the "Go Big" channel tier with 100 channels for $35 per month. If you sign up in time, the offer will remain valid each month until you cancel. But that $35 rate is not the long-term pricing for 100+ channels. DirecTV Now offers step-up subscriptions that include other channels and content for a higher monthly cost. ATT has signed programming agreements with nearly all major networks with the exception of CBS and Showtime; negotiations with those companies remain ongoing. DirecTV Now allows customers to watch up to two streams simultaneously. HBO and Cinemax can be added to any of these packages for just $5 extra (each) per month. DirecTV Now is "zero rated" for the company's wireless customers, so regardless of how much time they spend streaming, that activity will have no impact on data usage for their monthly bill. Importantly, while these are the subscription rates as of today, the company is being straightforward about the possibility of increases in the future. ATT also plans to air original shows including a Taylor Swift series.
