Marketplace’s first-ever kids podcast is out next week! In collaboration with “Brains On!,” “Million Bazillion” helps dollars make more sense. We’re tackling the big questions, like: Who invented money? How do you get your parents to agree to buy something you want? How do advertisers make you want what they’re selling — and how do you take your brain back? And why do things like pizza cost what they do? Host Jed Kim will help answer all these questions, with help from super-smart experts, kids and some famous friends. The first episode drops July 21! Here’s a trailer.
