I'd be interested in a breakdown of what contributes to those totals, sites like Youtube have a huge share in Video so it's not that out there to suggest that a single change they make could have such a huge impact internet wide. I know Youtube have been HTML5 for a while now so it isn't them, but it could be a similar site! Edit: oh, I think I misread. They're counting individual videos, not sites. So while Youtube has HTML5 available to everyone not all videos support it. My mistake, disregard.
