Programmatic podcast ad spending in the US, which we are forecasting this year for the first time, is growing at a fast rate from a small base. We define such ad spending to include podcast ads that are transacted and fulfilled via automation. Spend will double from last year to $31.3 million and reach $106.5 million by 2022.
Just 4.0% of total US podcast ad spending will transact or be fulfilled programmatically, up from 2.2% last year. That figure will increase to 8.0% in 2022.
There are multiple reasons why programmatic has been slow going into podcasts:
Nearly half (47%) of US podcast advertising was purchased on an annual rate in 2019, and 31% was purchased quarterly, according to the Interactive Advertising Bureau (IAB). Some 21% was bought on a scatter basis. And only 1% was purchased programmatically.
When so much inventory is purchased well before a campaign runs, it restricts programmatic’s role.
