$4 Billion in U./S. Mobile Ad Spending in 2015

Total U.S. mobile ad spending will grow from $790 million in 2010 to $4 billion in 2015. During the same period, BIA/Kelsey projects the local portion of that total to increase from $404 million to $2.8 billion. This makes locally targeted mobile ads 51 percent of overall U.S. mobile ad spending, growing to 70 percent by 2015.

There's a very good reason why Google is interested in what mobile devices can enable, in terms of advertising and promotion. There is a big, and growing local advertising business that typically has been dominated by phone book ads, direct mail and local media advertising. But mobile devices are widely seen as providing a better channel, in part because they are sensors, able to interact with other devices and servers, and in part because they can be used to deliver highly targeted messages, with instant interaction, in real time, in a way that other existing media simply cannot.
