According to MacRumors, Parks Associates has revealed figures from a recent research that depict Apple Inc. In terms of usage, however, 20 percent of U.S. households are said to own and regularly use a streaming media device. This makes sense given that iOS-powered Apple TV models have been on sale for a few years now.

Amazon managed to take the third place, increasing its US sales to 16 percent.

A report from Parks Associates on streaming media devices reports that four brands – Amazon, Apple, Google, and Roku – accounted for 86 per cent of all units sold to US broadband households in 2014. The second place was occupied by the Chromecast, which sold about 23 percent of the TV streaming devices on the market. While Roku’s flagship streaming box costs $99 – which is more expensive than the $69 Apple TV – it sells a streaming stick that’s only $50. Importantly, Apple ceded its No. 3 spot to Amazon.com (NASDAQ:AMZN), as the e-tailer jumped in previous year with Fire TV and Fire TV Stick.
