From 2006 to 2009, Internet ad spending will grow stronger than other sectors in North America, Western Europe and the Asia Pacific region, according to ZenithOptimedia, SFN's World Digital Media Trends 2007 reported.

In the Asia Pacific region, cinema and outdoor will also see high growth rates. In North America, cinema, TV, magazines, and outdoor are growing steadily. As for Western Europe, Internet is the only media with an accelerated growth potential.

Based on ZenithOptimedia's data, Internet spending, however, will remain a small portion of all ad spending, according to the report, World Digital Media Trends 2007, released by SFN and the World Association of Newspapers.
