I recently read that in the early days of FedEx, during the late 1970s, executives in Manhattan corporate offices discovered that employees were using FedEx to deliver documents between floors of their buildings because it was faster and more reliable than the interoffice mail.

Imagine, a package gets picked up by the FedEx man on the 20th floor, he takes it down to the street to his truck, drives it to the airport, where it gets flown to Memphis that night, just to turn around to New York in the early morning, where it gets driven back to the building, and delivered to the 19th floor.

Overnight! The magic!
