A recent report by Edison Research reveals that 84% of Americans aged 13 and older engage with ad-supported audio daily. The data, based on Share of Ear statistics, encompass various platforms, with AM/FM radio leading the way. This category includes podcasts, ad-based streaming services like Spotify and Pandora, spoken-word channels on SiriusXM, and free use of YouTube for music videos. Impressively, 82% of the typically challenging 18-34 age group in the U.S. are reached by ad-supported audio daily, emphasizing the effectiveness of audio advertising with younger audiences. When observed over a week or a month, the reach is expected to surpass 90% of all Americans. The findings suggest that advertisers seeking broad message dissemination should consider increasing their investment in audio advertising, particularly when targeting younger consumers.
