While the online video audience is still dwarfed by TV, it disproportionately pulls in younger viewers who have largely abandoned traditional TV in favor of digital and on-demand alternatives. In that vein, Randy Kilgore of Tremor video said he’s heard some broadcast networks won’t guarantee the 18-34 demo for advertisers anymore. If that’s true, and Tremor is able to guarantee that audience, then it’s got an edge for the much coveted slice of the audience. Carat’s John Wolff agreed online video represents a way to broaden reach, picking up viewers who you’re not going to get through TV.
