Does anyone know why the flight number changed from this ad and the REAL one that aired during the superbowl (flight status of DL 8601 vs AA120)? It's also strange that the date stayed the same but the time changed.

Perhaps it's because there are trivial results (see the "old" ad)? The old one has results for atlas sound and acrylic adhesive.

I don't know why this point stood out to me - are there any other changes I didn't notice? http://www.hulu.com/adzone/watch#50032769
