While other advertising verticals saw recent declines in growth, it seemed as if internet advertising would continue to be invincible. Well, it looks like the kryptonite just caught up with our Superman.

The Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers just released new U.S. quarterly numbers showing a 5% decline compared to the same period in 2008.

Microsoft reported its first ever year-over-year quarterly drop in revenue, in its entire 30-year history!

I’ll let that sink in for a second.

In its three decades of existence, Microsoft had never before seen a year-over-year quarterly drop, so if you needed a sign of just how bad this recession is, this is it!
