I ran into Drew Ianni, Chair for North America/Asia Pacific for Ad:Tech at the show yesterday. He told me they had 14,400 pre-registrations for the San Francisco event, which is a record for them. I was at the event and thought it was good - attendance was great, there were a number of interesting companies at the event with significant presences (e.g. Rubicon Project brought pretty much their whole company). Some were surprising (like a new adserver debuting… hmmmm) and we’ll have more to say about the event and some of the companies we met there.
