1	The hamburger is one of the most popular foods in America.  It is so popular that it could even be the symbol of America.  There are many reasons for this.  It is easy to make, cheap, delicious, and quick and easy to eat.  On average, Americans eat about three hamburgers per person a week.
2	Where and how did the hamburger begin?  No one knows for sure, but the combination of burger and bun probably started in America.  There are many stories.  According to one, in 1885 two brothers were selling food at a festival in the city of Hamburg, New York.  One day they ran out of pork, so they decided to use ground beef.  They did not like the taste, so they put in coffee and sugar to make it taste better.  Then they added two pieces of bread so people could carry the food.  Someone asked, gWhat do you call this?h  The brothers did not know.  One of them looked up and saw the sign gHamburg Fair.h  He decided to call it the gHamburger Sandwich.h  In time, hamburgers came with salt, pepper, ketchup, and little pieces of onion.
3	In the 1920s, hamburgers became even more popular.  In 1921 the first restaurant chain to sell only hamburgers opened.  It was called White Castle, and sold hamburgers for five cents each.  The first cheeseburger came in the 1930s, and was made by just putting a slice of cheese on top of the meat.  Once the cheese melted, the burger had a completely new taste.  Since it was so easy to carry, many people ate their gburgersh while driving.  The first restaurant with a drive-through opened in California in 1948.
4	In the 1960s, many toppings were added to the hamburger such as tomatoes, lettuce, onions, and pickles, and it became known as the gCalifornia Burger.h  Now, with many more toppings such as bacon, avocado, chili, mushrooms, and eggs, the hamburger is more popular than ever.  And yet even after a century, the basic hamburger is still the same.
