No, but neither do Roku. All three participate to embed their software (and hardware, probably) on smart TVs that other people make.

Roku makes TV, as well as Amazon.

All 3 make streaming devices (Stick, set-top box, etc).

		Show me a listing for a Roku made TV? All the ones I've seen are for like a TCL Roku tv. Same for Amazon, usually the same makers. n/m I do see that Roku sells tvs under its own name now. That's a change from the last time I looked.
