A Brief History of Snack Vending Machines
The concept of automated retail dates back to ancient times, but the first commercial snack vending machines appeared in the late 19th century.

Early Beginnings (1880s-1920s): The first known vending machine was invented in London in the early 1880s, dispensing postcards. By the 1920s, machines selling gum and candy became popular in the U.S.
Mid-20th Century Expansion (1950s-1970s): The rise of processed snacks and canned drinks led to a boom in snack vending machines in workplaces and public spaces.
Digital Revolution (2000s-Present): Modern machines now feature touchscreens, cashless payments, and real-time inventory tracking.
