Serving non-rich media in explandable slots?
Can somebody please help with a rising star/rich media question?
Specifically, I'm wondering if it is possible for publishers to serve a 970x250 non-rich media creative in a 970x250 rich media expandable "billboard" slot. Meaning, if a publisher can serve the rising star 970x250 rich media expandable creatives can they also serve 970x250 non rich media creatives if that is what the advertiser has. And if so, any details on execution is greatly appreciated.
