The global advertising market grew to just over US$600 billion in 2007, according to The Kelsey Group, the leading provider of research, data and strategic analysis on directional and interactive local media. The firm expects global ad revenues to grow at a compound annual growth rate (CAGR) of 2.7 percent and reach US$707 billion in 2012, propelled in large part by considerable growth in the interactive segment.
Interactive advertising, which comprises search (including local search), display advertising, classifieds and other interactive ad products, grew its share of global advertising revenues from 6.1 percent in 2006 to 7.4 percent in 2007. By 2012 Kelsey Group analysts expect the interactive share of global ad spending will reach 21 percent.
