The audio streaming and podcasting industry has grown significantly since the introduction of the iPod in 2001 and services like iTunes, Pandora, and Spotify. It is expected to have a compound annual growth rate of 18.49% through 2027. Spotify currently has the largest market share of any audio streaming platform, attributed to factors like its wide music catalog, brand recognition, and use of a freemium subscription model. While growth opportunities exist in emerging markets and new technologies, the industry faces challenges from high content licensing costs, competition, and piracy.
