“We don’t pretend to have the answer to what’s the killer way to advertise on mobile,” he said. “Right now we’re going with these banners and pre-roll to see how it works. We’re going to get feedback. It’s very possible we’re going to go with a different set of ad products.”

Action Engine provided the technology platform for Mobile. That platform requires consumers to have a data plan via their wireless carrier and is limited to Windows Mobile and Java devices. Action Engine said it will eventually work with BREW-enabled handsets.
