The Evolution of U.S. Flags in 80 Seconds

The American flag is one of the world's most recognizable symbols, but it didn't always look the way it does today.

Before we had the current American flag, there were many versions, featuring different combinations of stars and stripes, that flew throughout history.

The stars and stripes are a symbol of our country's history and some iconic moments that have stood the test of time. One of the most recognizable moments in American history was the raising of the U.S. flag at Iwo Jima during WWII. The moment was captured on camera by Associated Press photographer Joe Rosenthal in February 1945.

The flag is also a symbol of exploration. It was planted on the moon during the first landing by Apollo 11 astronauts in 1969.

The flag even has its own day -- each year Americans celebrate flag day on June 14.
