I was reading these intriguing stories behind a group of great logos 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 very
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 signs on the side
of the company's then walkup 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 Steve 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 rainbowcolored silhouette(轮廓)of an apple with a
bite taken out of it. And then the rainbowcolored apple was replaced by the onecolored 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 threepointed 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.
Adidas
The Adidas logo, which was created by the founder of the company Adi Dassler, represents
mountains, pointing towards the challenges that are seen ahead and goals that can be achieved. The logo
was used for the first time in 1967.
