AT&T has announced that they will be launching a streaming only TV service under the DirecTV brand, which they aquired last year. The new service will be available in three tiers: DirecTV Now, DirecTV Mobile, and DirecTV Preview. DirecTV Now will be the primary package which will offer most of the content available through today’s satellite based DirecTV, including premium add-on options. DirecTV Mobile will be priced lower than the Now package and will only be available through smartphones. Possibly the most innovative of the three options is DirecTV Preview, which will be a completely free tier supported by ads. AT&T has not revealed pricing, nor a release date, apart from saying the new service will launch later this year. Likewise, the telecommunications company has not announced which devices will support the new service, but there’s a pretty good chance we’ll see it arrive on the Fire TV, considering rival Dish Network’s Sling TV service is popular on Amazon’s streaming box.
