OpenX, an open source ad server for web publishers, released statistics today to show its strong recent growth - especially in the last 6 months. We interviewed the CEO of OpenX, Tim Cadogan, about the data. We also wanted to know how OpenX compares with Google's competitor Ad Manager, and we discovered how exactly OpenX will make money.

According to OpenX, as of December 2008 more than 300 billion ad impressions now run through its software every month. Its core product is still the open source OpenX Ad Server - version 2.6 was launched August 2008 and included a new API. This product has had more than 10,000 active downloads and is getting a 25 billion monthly ad impression run rate.
