Despite a worldwide recession (or maybe because of it), ad dollars continue to flow online. GroupM predicts that global Internet advertising will grow 11% next year to hit $65 billion, accounting for 15% of all ad sales. In the U.S. online ad spend will grow 7% next year, and make up a 17% share of all ads sold. The driver for U.S. growth will be search and video ads, GroupM said, which will gain as traditional media ad sales continue to decline. Display ad share of online sales in the U.S. will continue its downward trajectory, hitting 34% share next year, down from 35% this year and 39% last year. Worldwide, mobile advertising will jump 19% next year to $3.3 billion, making up 6 percent of all digital spending. "Despite the recession and the budget-cutting mindset advertisers are in, we are still seeing a net increase in digital investment," GroupM's Adam Smith told ClickZ.
