Political advertising buys are focused on the measurables: Nielsen viewership reports, radio ad plays, voter households dialed, mailers delivered and, above all, polling and voting results.
Out-of-home (OOH) advertising (billboards, street furniture, digital place-based media, cinema, street teams, etc.) has become increasingly measurable, is able to reach a hyper targeted demographic and is an effective compliment to tv, print, radio and mobile political campaigns.
