Mobile ad-network InMobi has released its Super Bowl XLVI Mobile Consumption Survey showing that, not surprisingly, mobile engagement was high during one of the most important advertising events of the year.

According to the survey, nearly 40% of respondents used mobile devices in response to TV ads and 45% estimated that they spent 30 minutes or more on their mobile devices during the game.  Interestingly, the survey showed that almost twice as many respondents used their mobile devices during the first half of the game compared to the second half – a powerful take-away for advertisers indeed.

“Mobile is an amazing channel for reaching consumers when they are in a lean-back entertainment-oriented mindset,” explained Anne Frisbie, Vice President and Managing Director, North America, for InMobi.  “Savvy advertisers will allocate more dollars to mobile advertising, either in conjunction with TV ads or through mobile-only advertising campaigns during similar sporting events and key holiday weekends throughout the year.”  Other takeaways from the survey include:

39% used their mobile device in response to a TV commercial during the game by doing one or more of the following: discussing commercials, getting more information about an advertised product, or watching TV ads again. 30% reported using their mobile devices most during commercials. 27% downloaded a Super Bowl app.
