According to media guru Gordon Borrell, local mobile advertising is set for steep growth as budgets are allocated to mobile advertising. While speaking at the MediaPost Mobile Summit,  Borrell said desktop ad budgets will shift to mobile in the next five years, propelling U.S. local mobile ad revenue to increase from about $2 billion this year to about $24 billion by 2016. Borell estimates that 88% of all local online advertising will be delivered on a mobile device.
