I know some poeple have problems with McDonald's, but it really is incredible how long its been around, since 1940. 
Really
Yes! it was opened by Richard and Maurice McDonald in San Bernardino, CA! 
In 1940?
You got it! And it actually started as a hot dog stand. Burgers weren't added to the menu until later at only ten cents per burger. 
So it started as a hot dog stand? Fine grass to grace story 
I know, it's incredible. Especially when you think about the fact that McDonald's is available internationally in 119 countries.
