How Walmart is going all in on artificial intelligence

As the digital era continues to turn retail on its head, Walmart's story is particularly interesting, as the brand is somehow both the challenger and the incumbent. Walmart has been the world's largest retailer since 1988, but as Sears proved, prominence isn't permanent. The retailer had a series of disappointing quarters, seemingly on track to become Amazon's biggest casualty. Galagher Jeff, the company's VP of Merchandising Operations and Business Analytics, even said so when he spoke at NRF 2019: Retail's Big Show in New York City earlier this week. "We had a business that was successful and we stopped taking risks," admits Jeff.
