The Internet Advertising Bureau and Price Waterhouse Coopers just released their annual online ad revenue research report for 2009. This report is widely regarded as one of the best indicators of trends in the online advertising sector. For those of us in the sector it never seems to be much of a surprise but it is always good to benchmark our progress against previous years and other industries.

I wanted to highlight two key data points for our blog readers.

First, I thought it was important to show how the pricing models used in online advertising have changed from 2008 to 2009. As you can see from the chart below, performance based pricing models (led by search marketing of course) continue to lead the way for online advertising growth while CPM based pricing models continue their slow decline.

Data like this makes me proud that NETexponent has been a leader in the Performance Marketing arena since 2001.

Another interesting component of this research shows the growth of online advertising from infancy until now compared to the same first few years of TV Broadcast and TV Cable advertising. This chart is pretty amazing and really puts into perspective the aggressive gains in online advertising.
