A milestone in delivery by drone

Starting today, drones shaped like miniature airplanes will drop packages of 4 pounds or less in customers' yards when they order from a Walmart Neighborhood Market in Northwest Arkansas, Worth Sparkman of Axios NW Arkansas reports.

Why it matters: The era of ubiquitous delivery by drone is inching forward, with scattered pilot programs involving pizzas and other light shipments — and the imprimatur of Walmart on this service is a big deal.
