DoubleClick's third-quarter "Ad Serving Trend" report, released yesterday, echoed the company's belief that online advertising is finally assuming some predictable characteristics--proof, according to
the company, that the medium is maturing. The size of its rich media component, as a percentage of all ads served, remained at a stable, but stagnant, 43 percent throughout the year. On Oct. 31,
DoubleClick announced it hired Lazard to explore strategic options, including the sale of all or parts of its business.
