For those over-the-top streaming device hopefuls like Amazon Fire TV, Apple TV and Chromecast, here’s some promising news: A sharply increasing number of consumers are streaming digital content on their big TV screens.One-third (31%) of respondents of a new study now say they spend at least some TV viewing time streaming broadband content to the TV set, according to New York-based Horowitz Associates.Much of this comes from modern TV set technology, which is more easily capable of accessing that content -- either through advance smart TVs or recent HDTV sets that can accept set-top-box/dongles equipment.Horowitz says nearly two-thirds (62%) of TV content viewers either own a smart TV or have the capability to stream content to their TV through another device.This year, alternative viewing of TV content has grown with streaming-to-TV grabbing the biggest gains. In 2014, 10% of TV content is being streamed to TV versus 5% in 2013. Some 6% of TV content is being viewed on a computer in 2014, against 5% a year ago. And 4% of TV content is taking place on a mobile device; 3% in 2013. TV content viewers say they spend 20% of their overall viewing hours streaming content, compared to 13% in 2013.The data comes from Horowitz’s “State of Cable & Digital Media” report, an annual, syndicated survey focusing on consumer behaviors towards and adoption of new television, broadband, and mobile technologies among TV content viewers.
