DirecTV Now, the online TV service, has recently dropped support for the 1st generation Amazon Fire TV and the 1st generation Fire TV Stick. When DirecTV Now first arrived on Fire TV devices in late 2016, it was available on all Fire TV models, new or old. Now only the 3rd-gen Fire TV, 2nd-gen Fire TV, 2nd-gen Fire TV Stick, and Fire TV Edition televisions are listed as compatible with the app.

Of the four competing online TV services, which includes Sling TV, Hulu TV, and PlayStation Vue, the DirecTV has always had the worst user reviews, so it seems like their app development team might be lacking. If you currently have DirecTV now on your 1st-gen device and it’s still working, if you uninstall it or factory reset your Fire TV, you will not be able to re-install the app.
The original Fire TV, which is the oldest model in the lineup, just turned 4 years old this month. Amazon is, thankfully, continuing to fully support it by still pushing out software updates that add the same new features that newer Fire TV models are receiving. It’s inevitable that, at some point, Amazon will stop updating older Fire TVs. When that happens, it’s safe to assume apps will also stop being updated for those older Fire TV models.
It doesn’t make much sense at all for DirecTV to stop supporting the 1st-gen Fire TV right now. I can understand not supporting the 1st-gen Fire TV Stick because it has a significantly weaker CPU compared to all other Fire TV models, but the 1st-gen Fire TV is more powerful than the 2nd-gen Fire TV Stick, which DirecTV Now still supports. Both the 1st-gen Fire TV and the 2nd-gen Fire TV Stick run the same version of Fire OS 5, so it just seems lazy on DirecTV Now’s part to support the one and not the other.
