I find it interesting that basically 100% of videos were from spammers (spare me the rounding error anecdote) so the CTR for video spam is "about" two orders of magnitude lower than the supposed (although highly gamed and faked) CTR for banner ads which are also by definition 100% unwanted spam.

So are there really two orders of mag of fraud in the bigger industry of banner ads, or despite popular belief is video two orders of mag less compelling than static banner ads or email spam... Something doesn't add up.
