Speaking at the IAB Engage event in London last week, Falco said: "Online is getting increasingly complex and we need to fix this to make it easier to do business. There are not enough standards in display advertising. We need to have common display ad sizes. That's something the IAB can help with."
Falco made the call to action after confirming AOL's takeover of ad technology firm Quigo for around $300m. Speculation had been rife that AOL would follow its $200m-plus purchase of behavioural targeting firm Tacoda with a Quigo deal to further boost its ad targeting arsenal.
