50 Million Streaming Devices by 2017

According to Parks Associates, 10% of U.S. broadband households purchased a streaming media device, either a streaming media player or stick, in the first three quarters of 2014, already matching sales from 2013. The research house expects 25% of U.S. broadband households to have a streaming media player by 2015, and nearly 50 million globally by 2017.

"Nearly 50% of video content that U.S. consumers watch on a TV set is non-linear, up from 38% in 2010, and it is already the majority for people 18-44," wrote Barbara Kraus, Parks' director of research.

Parks says Roku is still the leading brand with 29% of sales, but Google Chromecast (20%) has supplanted Apple TV (17%) in second place. New entrant Amazon Fire TV is in fourth place with 10%.
