After launching a video ad format earlier this year, mobile ad network Greystripe said Thursday it has already seen a 300% increase in the number of campaigns booked so far for the fourth quarter compared to all of the third quarter. Since June, more than 30 brands have run campaigns utilizing video ads on Greystripe, acquired by ValueClick in April.

The company boasted that it’s benefiting from “the massive shift of broadcast advertising budgets into mobile.” Huh? We’d like to see the evidence of that. On a less hyperbolic note, Greystripe said consumers have watched an entire video ad half of the time, with click-through-rates of between 1% and 3%.

Citing one example, Universal ran a campaign with Greystripe to drive trailer views and promote the August release of the "The Change-Up." The two-week campaign targeting men 18-34 generated almost 900,000 complete trailer views. Too bad it didn't help the film more at the box office.
