“Million Bazillion” listener Cora wants to know: How does a company buy another company? But before Bridget and Ryan can answer, Borpo, host of “Learning with Borpo” and CEO of a giant educational media empire, shows up with an offer to buy “Million Bazillion!” As the duo tries to figure out whether it’s a good deal or not, they’ll learn that buying (or selling) a company is more than just money on the table. It also involves intense negotiations, government regulations, and could change things for workers and customers.

In this episode, Bridget and Ryan travel through the history of money in front of a live audience of kids and families (for real!) to answer Sofia’s big question: What is the gold standard? Together, they explore this old money rule, how paper money became a thing, and why no countries in the world – not a single one – use gold to back their money anymore.
