It’s pretty well known that Facebook has over a billion users.
But did you know that iTunes hosts over a billion podcast subscriptions?
Podcasts have a CPM of $20-$45.
Facebook’s average of their top 5 sector CPMs (dating, deals, consulting, fashion, tech) is $0.25.
Podcasts attract 100x more advertising dollars than Facebook. But I think there’s another ~10x effect that comes from focusing on a niche. Segmentation is value.
