A new whitepaper from Parks Associates shows smartphones and tablets are expanding their role in video second-screen experiences, with 22% of U.S. broadband consumers checking or updating their social network on a smartphone or tablet while watching TV.

The whitepaper Moving from Second Screen to First Screen, developed for iMediaShare, examines the current and future role of mobile devices in TV viewing and entertainment experiences. It reports instances of mobile activities while watching TV increases significantly among Millennials, where consumers 18-34 are 70% more likely than other age groups to look up TV listings via a mobile device.

The mobile device is the implied peripheral in the second-screen concept, but increasingly it is the first screen consumers look at during a video-viewing experience. "The growth of OTT (over-the-top) services, pay-TV initiatives such as TV Everywhere, and increases in mobile apps have all contributed to this shift. Eighteen percent of U.S. homes with a smartphone or tablet use an app from their pay-TV provider to check TV listings, program their DVR, or watch TV programming.
