What did the first modern vending machines dispense?
Vending machine history goes back much further than you might think. One invention, which dispensed holy water, dates all the way back to ancient Greece. But the first modern, coin-operated vending machine was debuted by British inventor Percival Everitt in the 1880s. His machines, installed at post offices and train stations, dispensed paper products, including postcards, envelopes, and notepaper.
