I think we see almost one a day, someone confusing a Chinese Android box with the official Android TV OS. At this point I think Google has dropped the ball with marketing this device. It also doesn't help that these devices predate Android TV, heck even I had one. I think it comes down to name recognition as Android TV is too generic. Especially with YouTube TV streaming service. I hope something changes in the future.
Google has treated TV interfaces as a side project, never really putting their full weight behind any solution for very long; Google TV, Nexus Q, Android TV. They definitely dropped the ball but they don't really show any signs of picking it back up. They've chosen to put their money into Chromecast, (Google Cast?) for better or worse. Probably since it requires less investment and fewer resources.
They've at least updated the launcher interface for Android O, but I wouldn't get my hopes up about them really marketing it or making it be an industry-leader in 10-foot interfaces.
