How did McDonald’s expand from a single restaurant into an international chain?

McDonald’s began as a drive-in restaurant opened by brothers Maurice and Richard McDonald in 1940 in San Bernardino, California. In 1948, they revolutionized their business by introducing the Speedee Service System, an assembly-line format designed to produce high volumes of food at low prices.123

The transition to an international chain was driven by Ray Kroc, who visited the brothers' restaurant in 1954 and was impressed by their efficiency. Kroc established a franchise model, opening his first location in 1955 in Des Plaines, Illinois. He emphasized strict standardization of operations and implemented rigorous employee training programs to ensure consistency across all outlets.3

Kroc eventually bought out the McDonald brothers in 1961. The company continued its global expansion by adapting its menu to local dietary customs—such as omitting beef in India—and introducing innovations like clean public facilities and orderly queuing in various international markets. By the early 21st century, McDonald’s had become a symbol of global consumer culture, operating thousands of restaurants worldwide.345
