Advertsing prices relatively stable in Q4 2008

PubMatic just released its Q4 2008 figures for eCPM advertising pricing. You can find the full report here. While it is not a fully representative benchmark, this report seems to be directionnaly correct. The main message I take out is that Q4 prices are relatively stable vs. Q3 (-3.7%, i.e., within the margin of error of such a benchmark). This is a good suprise given the economic environment but it could be due to seasonal effect (i.e., holiday advertising). There is in any case a continuous downward trend of ad pricing when we look at the figures since Q4 07.
