Brian Alexander writing in The Atlantic:

There were other glass companies in Lancaster, drawn there by cheap natural gas. But following a 1937 merger with the New York-based Anchor Cap and Closure, The Hockin, now Anchor Hocking, grew into the world’s largest manufacturer of glass tableware and the second-largest maker of glass containers such as beer bottles and peanut-butter jars. It even played a role in the invention of late-night TV, in 1950, by sponsoring the pioneering NBC show Broadway Open House. Anchor Hocking became Lancaster’s largest employer by far, the rare Fortune 500 company based in a small town. At its peak, it employed roughly 5,000 people there, including executives in the headquarters, and many more in plants around the country.

But then came the 1980s.
