How many podcasts exist?

How to get close to this number

Count from the barrier to entry. Publishing a podcast requires a microphone and a free hosting account, so the number of people who have tried is enormous. Millions is the right scale for anything that costs nothing to start and appeals to a broad population.

The active share in the explanation is the number that matters: fewer than one in ten have published anything in the last three months. The rest have stopped, and the median podcast never reaches its seventh episode — a statistic that describes the shape of amateur creative output more honestly than any total.

This is the same pattern as Steam games, online stores and Twitch streamers on this site, and it is worth naming as a general law of zero-cost platforms: supply is enormous, attrition is brutal, attention concentrates in a tiny top tier, and the median participant abandons the project within a few months. The total count measures ambition rather than activity.
