The legendary comic book character known as
Superman has been captivating readers and audiences for
75 years. Over the years, the character has appeared in countless comic books, cartoons, radio programs, TV shows and movies, as he fights his never-ending battle for truth, justice and the American way. But what that means and what that looks like has evolved many times over the years, as various artists, writers, actors and others have put their spin on the world's ultimate superhero.

Of course, the basics of Superman's appearance haven't changed too much since the beginning. Show a picture of anyone in a "super suit", and kids and grown-ups alike will recognize him instantly. But that doesn't mean the suit hasn't been modified a few hundred times over the years! Designers have played with various shades of blue and red, and the new movie,
Man of Steel, is the first depiction I'm aware of where the Big Blue Boy Scout doesn't wear his red underwear on the outside of his outfit!
Perhaps the one piece of Supes' costume that has gone through the most changes is the "S" shield/logo he wears on his chest. The colors, shapes and sizes of the logo have been reworked and revisited, and are often the subject of scrutiny and criticism from fans whenever a new version is revealed. Besides the appearance of the emblem, the significance has also evolved with time.
