Popeye is an iconic character from a cartoon that was created in 1929.  He’s a sailor who lives on an island full of food.  Every episode is about him getting all the food he can eat for free, and then a little bit more.

How did the hamburger become such a popular fast food meal in the USA?
user
Hamburger is short for “Hamburg steak”, which is a German dish made with ground beef.  It became popular in America after German immigrants settled in Wisconsin and Hamburg, NY.

So from there it just spread out?
user
That’s about right.  The meat portion of the burger was already being popular in the 1800s.  It’s a tough meat to cook over a fire, so most people made it into patties.  It was around this time that the idea of taking it to the streets started gaining traction.  The sandwiches were still large though, and served on bread.

I bet hamburger was a lot cheaper than it is now too!
user
That’s right.  Hamburger cost about 2 cents in 1900.

Wow! That reminds me of Wimpy from Popeye.
