Netflix Takes Big Chunk of Viewing but May Not Hurt Ad-Supported TV

Ownership of dedicated set-top or plug-in devices that access Netflix, YouTube and other web-based services on big-screen TVs has increased tenfold since 2010 to 21% of U.S. households, according to a new report by GfK. But while the trend is fueling big increases in viewership of video on subscription services, particularly Netflix, it's not having much impact on "regular" ad-supported broadcast or cable TV yet, according to David Tice, a senior VP leading the media sector at GfK.
