Google TV
Google TV is the search giant’s move in the streaming market, but as of yet they haven’t made much impact, with expensive systems and a small user base.
Yahoo Connected TV
Yahoo has seen its Connected TV platform baked into more than eight million TVs, but only a million of those owners are using the service each month.
Boxee
Boxee’s doing a bit better, with more than two million users! Although most are using the old Boxee app rather than the Boxee Box.
Roku
Roku has sold over 3 million streaming boxes, and they feature content from Disney, HBO, Major League Baseball and the NBA.
Apple TV
The most successful pure streaming box out there is the Apple TV, with 6 million units sold worldwide. Of course, this is small potatoes compared to sales numbers for Apple’s other products.
Game System Networks
Both Xbox Live and the PlayStation Network have far more users than Apple TV, with 40 million and 90 million, respectively.
Apple TV vs. Roku
Out of all these options, the leaders in pure streaming boxes are Apple TV and Roku. Choosing which is best for you may depend on whether you are heavily invested in iTunes as a media source, or if you are swayed by features offered by Roku, but not Apple.
