A year's worth of research from Simmons, a media consultancy, shows that Internet video watchers are 47 percent more engaged by the advertising they watched than were traditional TV viewers, according to MediaPost. The same study found that viewers were 25 percent more engaged in the content on the shows as well.
Its good to have this confirmed with data, our instinctive (and empirical) observation is the same. Clearly over time this difference will probably wane, but its a good thing to have in a fledgling industry.
And as Ars Technica notes, the flow of Ad dollars online is still occurring......
