How are adverts from today inserted into old podcasts?

Question

Edit: how’s it done automatically? I’m not trying to learn I’m just intrigued

I.e. how come podcasts from 2018 have adverts for current products?

Same way YouTube shows adverts. Same way TV shows adverts. They stop the thing you’re watching, and play the advert instead for a bit. Then they restart the thing you’re watching.
