Facebook takes on food delivery, challenges Uber and others

File- This Jan. 17, 2017, file photo shows a Facebook logo being displayed in a start-up companies gathering at Paris’ Station F, in Paris. Facebook says ordering food for takeout or delivery is complicated, and it will help users save time by bringing a bunch of existing food-delivery services into its app and partnering with some restaurants directly. Of course, using Facebook to order food might prompt users to spend more time perusing their news feeds and seeing ads. (AP Photo/Thibault Camus, File)
