UPDATE 4-Jet.com falls by wayside as Walmart focuses on its website, online groceryWalmart Inc on Wednesday announced a sweeping overhaul at Jet.com, an online start-up it acquired in 2016 for $3.3 billion, after it failed to live up to the world's largest retailer's e-commerce ambitions. Walmart said it will integrate Jet.com's retail, technology, marketing, analytics and product teams with its own online business. Walmart's move reduces the scope and importance of Jet.com in its overall U.S. e-commerce business, which competes with Amazon.com Inc, according to interviews with six vendors, two consultants and three Walmart employees.
