NEW YORK (AP) — Slightly more than half of the people who watched the Sochi Olympics on NBC also used a computer, tablet or smartphone to get information about the games while the TV was on, the network said Wednesday.

NBC closely studies how Americans follow the action partly because the Olympics are a huge investment, but also to get a peek at how media habits are changing. This year’s takeaway: the multiscreen experience is rapidly taking hold and is doing so across all age groups.
