There was a time when the podcast was the new brat on the block: everyone could see it was a disruptive presence but nobody was sure how seriously to take it, or how long it would stick around. That was nearly 20 years ago. It has since grown up and owned its space so successfully that everyone wants a bit of it.
This summer, a YouGov survey found that 50% of British adults had listened to a podcast in the past year. The problem for those who make them, and hope to get rich by them, has been getting an accurate picture of their reach. But that too appears to have been sorted, with the launch last month of a quarterly chart listing the Top 25 titles.
