A recently published FCC filing shows a Google-branded HDMI dongle that's running Android TV. The device is listed with the model number "SN5B6AD" and it is described as a "4K ATV Stick." The mysterious device is listed as being manufactured by "Shenzen SEI Robotics Co. Ltd." The dongle itself features Google's signature "G" logo and it's accompanied by its own remote. The device appears to have a design that closely resembles a next-generation Chromecast, but it's running the Android TV operating system.

The puck-shaped Nexus Player is no longer available for sale from Google, as The Verge first reported. Other retailers haven't stocked the device for months. If you count the ill-fated Nexus Q, the Nexus Player was Google's third run at creating a set-top box, following a run of over-priced devices powered by the now defunct Google TV. The Nexus Player was first introduced in late 2014 as one of the first devices running Android TV. At the time, we said the player was a "fine first draft."
