Wax nostalgic about and learn from the history of early electronics. See articles from Popular Electronics, published October 1954 - April 1985. All copyrights are hereby acknowledged.

Waaaay back in the mid-1980s when I first became aware of Digi−Key, it was one of the relatively few electronics component suppliers that had a large on-hand stock of commonly used parts and provided fast shipping. Places like Newark Electronics and Allied Electronics also provided good service, but Digi−Key usually offered lower prices than the others. By the 1990s, I was placing orders at least weekly during circuit design projects. Digi−Key was founded in 1972 in Thief River Falls, Minnesota - the town that for many years often had the country's lowest recorded daily temperature. This 1/4-page advertisement appeared near the back of a 1974 issue of Popular Electronics magazine. By the mid-1990s, their multipage ads in electronics magazines were proliferating like today's Harbor Freight ads. Here's a bit of trivia I just learned: The company's name is a reference to the "Digi−Keyer Kit," a digital electronic keyer kit that founder Ronald Stordahl developed and marketed to amateur radio enthusiasts.

If you are a Millennial or younger, the reference to a "Reader Service Card" at the bottom might be an enigma. It was a cardboard mail-in insert where you filled in circles next to companies from whom you wanted information mailed to you (which was more often than not ignored). They were sort of the pre-Internet version of a 2-D scan code.
