Cadogan has been with Yahoo for five years and before that was at GoTo.com. He was the senior vice president for ad products and was instrumental in the Yahoo Panama launch. Cadogan was one of the major faces behind Yahoo and search.
The interesting part is that Tim Cadogan will continue to compete with Google, on some level. OpenX is an open source ad delivery product — I used it personally for years on my sites. As many of you know, about a month ago Google launched Ad Manager, a free, hosted ad delivery product. Since then, OpenX and Google are now competing in the ad delivery software space. In fact, I switched from OpenX to Google Ad Manager just a week ago.
