Amazon is beginning to launch its same-day grocery delivery service, Amazon Fresh, in New York, with service to one Brooklyn neighborhood starting today. Recode reports that the service will begin in Park Slope, a generally well-off neighborhood associated with city parents, and that Amazon intends to expand to elsewhere in Brooklyn from there. Amazon doesn’t say whether it’ll be launching in Manhattan, but same-day grocery delivery has long been a field that web companies have tried to crack — and should its experiments in Brooklyn succeed, there’s no doubt that Amazon will keep pushing forward.
