A few years back, I scraped data on podcasters from iTunes. The data was a bit underwhelming and made me realize that podcasters can’t be a potential market. It is a bit dated but I believe is still relevant.

I scraped the data for about ~1.5M podcasters listed from iTunes. At the time of scraping -

1. 430K podcasters have not created a single podcast in the past year.
2. 550K podcasters have not created a single podcast in the past three months.
3. 340K podcasts created a podcast in the last month.
   1. Of those, only 190,000 have a podcast with at least ten episodes!
   2. Out of 190,000, less than 36,000 have any social media presence!

So, less than 50,000 podcasters were doing this professionally.

These numbers are a few years old, but I doubt they have changed by a lot.
