Who knows? Maybe the Apple TV has appeal. But the numbers show otherwise. According to new data from research firm Parks Associates, 37 percent of all streaming devices in the United States were made by Roku. Amazon's Fire TV sticks came in second place, at 24 percent. Google enjoys 18 percent with its Chromecast devices, and down the heap is Apple with just 15 percent, down three points from last year in the same quarter.

"Higher-priced devices, such as the Apple TV, have not been able to keep up with low-priced and readily available Roku devices, which can be found at Walmart for as low as $29.99," said the firm's senior analyst Glenn Hower.
