Online Ad Revenue To Touch $18.9 Billion

A proof that e-commerce has come of age appeared yesterday as JupiterResearch predicted online advertising would reach US$18.9 billion by 2010 -- almost double last year's gross of $9.6 billion. Much of that revenue growth will be stoked by search engine advertising, which garnered 40 percent of online ad sales in 2004, compared to 27 percent for display and sponsorship advertising and 18 percent for classified advertising.
