The only thing that matters when putting forth a Superbowl commercial is that the viewer stood around long enough to figure out who sponsored it

The Youtube attention statistics are a nice proxy for it but it didn't take into consideration the likelihood that a potential viewer lost interest before they knew what it was 'about'

Great points, and agreed. This is what the attention plot ventures to take into account

measure the trending of hashtags / mentions / youtube views of the commercial in the days following

This would definitely be useful to see.
