Total U.S. audio ad spend has recovered from the 14% decline that occurred between 2000 and 2010. Jack Myers TomorrowToday forecasts that, by 2020, total U.S. audio ad spend will exceed $20 billion, driven by solid growth in digital ad investment. Audio content has fared better than print-originated content in the face of new digital alternatives. Newspaper-originated ad spend declined by nearly 40% between 2000 and 2010. Unlike legacy newspaper-originated content, audio ad offerings (linear and digital) have maintained geo-targeting attributes combined with real-time content relevance. Audio advertising spend includes legacy & digital terrestrial radio and online-originated audio (Pandora, Spotify, podcasts, et al).
