A report released this week by Millward Brown takes a quantitative and qualitative look at multiscreen activity from a number of perspectives. The report is based on a global survey (n=12,000 respondents, 30 countries). The US sample was 444 people, with some behavioral monitoring and interviews. There’s a great deal of interesting material in the report, which is free.
While this has been asserted by others in the past, Millward Brown confirmed that in the US daily smartphone screen time has now surpassed TV. That’s also true worldwide. If one combines smartphone and tablet screen time the total exceeds TV by nearly an hour per day.
