Multitasking Super Bowl Viewers Visited Google, Facebook
Nearly one in seven (14%) of at-home Super Bowl viewers with Internet access browsed the Web at least once during the big game, up slightly from last year's 12%, according to separate research from Nielsen.
Time spent online for those multitaskers was up from 24 minutes last year to 29 minutes, with much of that concurrent time spent on social networks.
While watching the game, 36% of simultaneous users visited Google, 34% visited Facebook, and 30% visited Yahoo.
Facebook, which was visited during the game by 1 in 20 of all at-home Super Bowl viewers with Internet access, led among the most-visited sites in terms of simultaneous time spent, accounting for 19 minutes per user.
Meanwhile, Web users spent far less simultaneous time on Google (an average four minutes) and on Yahoo (seven minutes).
About the data: Data on simultaneous viewership reflects preliminary analysis of Nielsen's single-source measurement of the Internet and TV in Convergence Panel and select National People Meter homes.
