I was reading these interesting stories behind a group of great logos (标志) in the world. Personally Nike is my favorite one—it’s so simple. And I liked the stories behind them, which made me forget all other things. McDonald’s, Apple, Mercedes Benz and Adidas own great logos as well, and they are among my favorites.

Nike

In the Greek myth, Nike is the goddess of victory and the source of inspiration for soldiers. This logo represents the wing in the famous statue of the Greek goddess. Nike’s logo was designed by Carolyn Davidson in 1971 for $ 35, and was registered as a trademark in 1995.

McDonald’s

The logo was designed in 1962 by Jim Schindler to resemble the archshaped(拱形的) signs on the side of the company’s then walk-up hamburger stand. Later on, the two golden arches were combined together to form the M. The McDonald’s name was added to the logo in 1968.

Apple

There are different stories behind Apple’s logo. The first logo was a reference to the religious story of Adam and Eve, in which the apple represented the fruit of the Tree of Knowledge. One year later, the second logo was designed in 1977 by Steven Jobs and Ronald Wayne, and it described Sir Isaac Newton sitting under an apple tree. This logo didn’t stay long. One year later it was replaced almost immediately by graphic designer Rob Janoff’s “ rainbow apple”, a rainbow- colored silhouette (轮廓)  of an apple with a bite taken out of it. And then the rainbow- colored apple was replaced by the one- colored logo in 1998. It has not been changed so far.

Mercedes Benz

The Mercedes Benz logo, which was originally created by Gottlieb Daimler in 1909, consists of a simple description of a three- pointed star that represents its rule of the land, the sea and the air. The company was founded by Gottlieb Daimler and Wilhelm Maybach. Marcedes is the name of Maybach’s elder daughter, while Benz came as a result of a combination with Benz, Cie. and DMG in 1926.
