So there is life after the "468." Specifically the 468 X 60 banner ad. This was one of the topics at Ad:tech. Digitas’ CCO Mark Beeching has a great observation, that the shift away from traditional banners is symptomatic of the move away from the interruptive model of advertising.

Good example of this is Intel’s and IBM’s use of allowing a banner ad to be a way to interact with customers. More specifically a real-time chat. Story in AdAge here.

Interesting factoid: Digitas created the first ever banner ad, 12 years ago.
