Research: Mobile ad spending could reach $14.4 billion by 2011

Spending on mobile advertising could reach $14.4 billion by 2011, accounting for one-fifth of global spending on Internet advertising, according to a report from Strategy Analytics Inc.
“The outlook for mobile advertising spend has significantly advanced in the past 12 months,” said Phil Taylor, director of Strategy Analytics’ global wireless practice. “The supply of advertising inventory is rapidly increasing as mobile publishers look to develop advertising as a revenue stream.
“Major mobile network operators like Sprint Nextel, Verizon Wireless and Vodafone have all accelerated plans to sell advertising within their mobile media channels and advertisers appear to be responding positively,” said Taylor.
