DIRECTV NOW, AT&T's online-only streaming service, will launch in early November. That's according to AT&T CEO Randall Stephenson, who revealed the streaming service's timeline during a discussion of AT&T's planned merger with Time Warner.No official release date has been revealed, so all we know for sure is that November is the month.DIRECTV NOW will be an OTT MVPD service (that's “over the top,” which means via the internet, and “multichannel video programming distributor,” which essentially means the traditional pay TV style with multiple network channels). That puts it in direct competition with Dish-owned Sling TV and Sony-owned PlayStation Vue.Stephenson also bragged about DIRECTV NOW's price, which he said would be “radically lower” than its competitors. That price has since been announced. DirecTV will cost $35/month, which isn't any less than PlayStation Vue or Sling TV. However, DIRECTV NOW's reported selection of more than 100 channels would make it the cheapest on a per-channel basis.It's an exciting time for AT&T, which may soon acquire Time Warner (assuming the terms – which the companies have already accepted – are approved by regulators). The Time Warner merger would have implications for DIRECTV NOW, as Time Warner owns content providers like TBS and HBO.
