All tickets have now been sold for the Ad Trading Summit 2010. Attendees will receive a full summit agenda next week. If you missed out this time, please note that there will be another event in February, 2011. Details to follow on that shortly. Again I want to thank sponsors, AppNexus, Admeld, Vivaki and Quantcast, for making this event possible. And I look forward to a lively day of debate on September 23.
