If you've logged on to this page then the chances are that you're planning to join us for the IAB Europe Leadership Council here in London this week. The theme at this Leadership Council is Web 2.0 and its implications on the marketing strategies of advertisers looking to run campaigns across several European countries. We have brand new research from NetRatings, Q Research and Net Observer, as well as the findings of Microsoft's most in-depth of strudies. As the Co-Founder and Chief Executive of IAB Europe it's my pleasure to welcome you to London, and to the IAB Europe Leadership Council.
