Today Twitter launched a beta of Promoted Video ads, a service that will give brands a new set of video tools for uploading and distributing video on its platform. Interestingly, Twitter opted for a Cost Per View (CPV) ad buying model, only charging the advertisers by the play counts of branded videos. While the jury is still out on whether promoted videos will effectively create a more engaging brand experience on Twitter, advertisers will no doubt welcome this fair pricing model.
