I've been seeing more and more of these lately—placements that went live even though they were screwed up. It likely attests to the lack of experience talent in the field, and the habit of media companies of throwing young, untrained employees right into the mix of complicated ad serving tools without much beyond the 1/2 day intro. Reminds me a little bit of radio in the late 70's / early 80's, except that then the errors were usually because the dj was stoned or drunk or both.
