Anyone who has spent any time following the ecommerce industry and particularly Amazon and Walmart is familiar with the journalism of Jason Del Rey, who spent a decade at Recode documenting the transformation of retail, and also through his podcast Land of the Giants: The Rise of Amazon. He has now come out with a deeply researched and incisive book entitled Winner Sells All: Amazon, Walmart, and the Battle for Our Wallets, and he joined the podcast to share some insights of this most consequential era in retail, and where this clash of the titans might go from here.
