Roku announced today a milestone of 10 million units sold since 2008. The company said over 5 billion hours of content have been streamed since that year, with the average Roku owner streaming about 48 hours of content a month. While the number of Roku devices out there amount to only half as many Apple TV players sold (at last count 20 million reported in April, 2014), the number of channels available on Roku far surpass the approximately 40 options available for Apple TV. The blog announcement claims Roku devices stream 37 million hours of video per week compared to 15 million hours on Apple TV devices and 12 million hours on Chromecast. The newest streaming media player of the bunch, Amazon’s Fire TV, streams about six million hours per week, according to Roku. “Just over six years ago we shipped the very first Roku player to stream Netflix to the TV and now our players are synonymous with TV streaming,” said CEO Roku Anthony Wood.
