The fact that you've never heard of Roku doesn't really say much other than you either living in a country where Roku is not available, or living under a rock.

Roku tends to get a lot of retail space, so if you've walked through any walmart electronic section, or bestbuy, or whatever you're guaranteed to see them.

Before smart TVs took off there was only Apple TV and Roku. No Chromecasts or Fire Sticks. Meaning if you couldn't pay the Apple tax, you went with Roku to get your Netflix.
