Pandora has begun to test a new type of advertising format that allows listeners to respond to the ad by speaking aloud. In the new ads, listeners are prompted to say “yes” after the ad asks a question and a tone plays. The ads will then offer more information about the product or brand in question. Debut advertisers testing the new format include Doritos, Ashley HomeStores, Unilever, Wendy’s, Turner Broadcasting, Comcast, and Nestle. The ads begin by explaining what they are and how they’ll work.
