I just heard on NPR this morning (clip available here: http://www.npr.org/rundowns/segment.php?wfId=1420569 at the top of the page) Somehow, I don't think the studios will do this. EVen if they all agree on it, someone's gonna think "well, one little ad won't hurt". Someone else sees it, and puts in a slightly bigger ad.... and it's all rolling again. Is it even a good idea? I'm not sure.
