We've been saying for a while now — based on the evidence we've seen in certain European markets — that online video viewers are happy to watch a significant number of in-stream ads in exchange for access to high-quality content.  Today, we found yet more evidence of the same from a study conducted by Turner Broadcasting. Today, many of Turner's TV shows only run two or three in-stream ads each (generally less than 2 minutes of advertising per episode); but the broadcaster found that if it increased the ad load to the same volumes the shows feature on TV (as much as 20 minutes per episode) the number of users who dropped off was shockingly low. The CW network found the same in its own tests.

The bottom line: Get ready for more online video ads. Inventory will grow, prices will fall (at least somewhat), and overall online video ad spending will grow dramatically.

(As a side note, The New York Times' article in which this research is published takes aim at Hulu for hoping to "lighten up" the amount of advertising users see and repeats Hulu's accurate claim that it has less than half as much advertising as the same shows on TV — which is ironic, given that in my anecdotal experience Hulu has been more aggressive than any other US online video site in pushing more ads into its content; most of the ad breaks I see on Hulu these days contain two ads.)
