The wall street journal had this to say today:

"Internet Ad Spending Is Set to Top '05 High

NEW YORK -- Internet ad sales for the first nine months of the year are close to the amount spent during 2005, setting up the likelihood of another record year, the Interactive Advertising Bureau said.

At this rate, Internet advertising spending should reach $16 billion in 2006, which would eclipse last year's record of $12.5 billion, the IAB says. The IAB reported that the amount spent on Internet advertising from January to the end of September was $12.1 billion.

In the third quarter, $4.2 billion was spent on Internet advertising, representing a 33% increase from the year-earlier period. The third-quarter's ad revenues represent the largest ever spent on Internet advertising in any three-month period, according to the IAB, ekeing past the most recent record of $4.1 billion set in the second quarter of 2006."
