AT&T's internet TV plans don't stop with DirecTV Now, as it also highlighted two Go90-ish services during an event today. The already-available Fullscreen (previously mentioned as DirecTV Mobile) offers a $6 per month subscription video service intended to be social- and mobile-first (read: this is where some of those Vine stars went), and now AT&T mobile customers will be able to get a year of free access bundled with new or existing plans.
