According to data released at Advertising Week, nearly 50 million Americans now own smart speakers, and that figure could rise by 25% by the end of 2018. In fact, within two years 100 million consumers worldwide could have smart speakers in their homes and offices. These devices are transforming how Americans listen to audio, with users "asking" them to stream live audio, play podcasts and access on-demand content. Tellingly, comScore predicts that by 2020 at least 50% of all search will come via voice. With that momentum at its back, Cumulus Media-owned Westwood One, the nation’s largest audio network with over 8,000 affiliates, is expanding its voice app work into co-produced voice apps for its national brand partners.
