Undertone, which creates digital advertising solutions for brands, today released the findings of a Rising Stars research study that reveals awareness levels and buying intentions of agencies, marketers and publishers. The six Rising Stars ad units – Billboard, Portrait, Pushdown, Filmstrip, Sidekick and Slider – were released by the IAB in 2011. Undertone’s study is the first to gather perceptions of the units from both the buy and sell-side.
