The podcasting industry has been quietly booming, but traditional estimates have significantly undervalued its true scope. For years, the Interactive Advertising Bureau (IAB), a key reference for market sizing, pegged the U.S. podcasting market at $2.4 billion for 2023, focusing solely on audio advertising revenue in the United States. While this figure is substantial, it paints an incomplete picture, ignoring critical revenue streams and global markets. In 2024, a more comprehensive analysis reveals that the global podcasting market is worth a staggering $7.3 billion—roughly three times the IAB’s estimate.
