and if you've ever listened to one of Robert's (CZM executive producer and host of some of their flagships) other podcasts you might understand why companies don't want him doing ad reads.
I’m not even against pre-recorded spots by whoever the sponsor is if that’s his deal though the conversion rate on those are not as good. It’s just the completely random ads that the podcaster(s) don’t even know are playing on their show. The entire reason advertising on podcasting was more effective in the 2010s and early 2020s was because there was a little more trust with their listeners, there’s a relationship at play even if it’s parasocial. If they were actively reading on air, I assumed that they vetted the company and it at least passed the smell test (though plenty sure didn’t, I would say the bar was a little higher than other media formats).
