After the war ended, America witnessed the development of the suburbs, and new consumer trends emerged. More Americans were buying cars and shopping at suburban malls with large parking lots. UPS recognized that its role in home delivery services for department stores was limited, and its management pursued new growth opportunities.
UPS management sought to expand its breadth of services. In 1953 UPS began common carrier operations by providing package transportation services to the public in cities where the company did not require authorization by the state commerce commissioner or the Interstate Commerce Commission to do so. During the same year, Chicago became the first city outside of California in which UPS offered common carrier service. Amid the determined pursuit of common carrier service deregulation, the company reintroduced air service, offering two-day delivery to major East and West Coast cities in 1953. As with the previous effort, UPS shipments flew on regular commercial flights.
The expansion effort was fraught with challenges. Strict state and federal regulations limited access and entry to major markets. In some instances, shippers were required to transfer a package between several carriers before it reached its final destination. UPS faced unprecedented legal battles to obtain the proper certification to operate over areas wide enough to satisfy growing public demand for its unique services. Over the course of 30 years, UPS pursued more than 100 applications for additional operating authority. By winning these challenges, UPS effectively laid the groundwork for other delivery companies to compete in the marketplace. In 1975, UPS became the first package delivery company to serve every address in the 48 continental United States. This momentous convergence of service areas became known within UPS as the "Golden Link."
