when did mcdonald's start serving french fries
History of McDonald's In October 1948, after the McDonald brothers realized that most of their profits came from selling hamburgers, they closed down their successful carhop drive-in to establish a streamlined system with a simple menu which consisted of only hamburgers, cheeseburgers, potato chips, coffee, soft drinks, and apple pie.[3] After the first year, potato chips and pie were swapped out for french fries and milkshakes. The carhops were eliminated, making the new restaurant a self-service operation. Richard and Maurice took great care in setting up their kitchen like an assembly line to ensure maximum efficiency. The restaurant's name was changed again, this time to simply "McDonald's," and reopened on December 12, 1948.
History of McDonald's By 1991, 37 percent of system-wide sales came from restaurants outside the United States. McDonald's opened its first foreign restaurant in British Columbia, Canada, in 1967. By the early 1990s the company had established itself in 58 foreign countries, and operated more than 3,600 restaurants outside the United States, through wholly owned subsidiaries, joint ventures, and franchise agreements. Its strongest foreign markets were Japan, Canada, Germany, Great Britain, Australia, and France.
