McDonald's is a fast food company that was founded in 1940 
That's cool. I saw a movie recently on that.
It was operated  in 1940 as a restaurant by Richard and Maurice McDonald, in San Bernardino, California, United States.
fascinating! How did they get so big I wonder. 
The owners renamed and organised  their business as a hamburger stand.
I guess the "fast food" really got popular.
Something interesting happened In 1955, Ray Kroc, a businessman, joined the company as a franchise agent and proceeded to purchase the chain from the McDonald brothers
