New Jersey-based The Kelsey Group is forecasting that worldwide interactive advertising revenues will increase from US$45 billion in 2007 to US$147 in 2012. "It’s no surprise that the global advertising industry is experiencing a full-scale shift to mixed-media platforms, with interactive driving a significant share of overall industry growth," said Matt Booth, senior VP, interactive local media, The Kelsey Group. "We see Internet development-including increased subscriber/user access and broadband penetration-as a driver of both interactive advertising revenue as well as migration of traditional ad spending to new media platforms." During the forecast period (2007-2012), The Kelsey Group predicts that local search revenues will grow from US$2.1 billion to US$6.6 billion, and Internet Yellow Pages revenues will grow from US$3.7 billion to US$9.2 billion.
