A year ago, Roku and Apple TV dominated the market for streaming video devices, accounting for nearly 75% of all video streaming products sold in the US in 2013. But in the last 16 months, Google’s Chromecast and Amazon’s Fire TV devices have stolen a significant chunk of Apple and Roku’s business. This is according to a new survey from Parks Associates, which still puts Roku at the top of the pile, though the company’s devices now only account for 29% of streaming devices sold thus far in 2014.
