Companies have more than serious interest in targeted online advertising. An example of this is that in the last month four major deals were made: Google - DoubleClick, Yahoo! - Right Media, WPP Group - 24/7 Real Media and Microsoft - aQuantive.
Analysts from eMarketer are confident that global spending on targeted advertising will grow from $ 575 million in 2007 to $ 1 billion in 2008, and by 2011 the market volume will be $ 3.8 billion. An illustrative growth process is shown in the diagram.
