This IDC study forecasts spending on Internet advertising, excluding production costs, for the United States, Canada, Japan, and worldwide regions for the period of 2012–2016 and outlines historical spending for the years 2009–2011. Numbers are further broken down by advertising formats, including search, display, rich media, video, classified, mobile, and other advertising. Numbers are sourced from IDC's Worldwide New Media Market Model, 2H11 (Forthcoming).

"Advertisers keep pouring more money into online ads. This year, for the first time ever, U.S. advertisers will spend more money on Internet advertising than on print advertising," said Karsten Weide, IDC's Program VP of Media and Entertainment.
