IBM Logo - Design and History

The IBM logo is another logo that is easily identied, especially by anyone in the computer industry. IBM, has been known as "Big Blue" and they have simplified their logo over the years, and their name. What started as International Business Machines is now just "IBM" and the color blue has been a signature in their unifying campaign as they have moved to become an IT services company.

In 1972, the company introduced a new version of the logotype. Designed by Paul Rand, horizontal stripes now replaced the solid letters to suggest "speed and dynamism." In the intervening quarter-century, the basic design has remained constant, one of the most recognized logotypes in the world, and a design that has been widely imitated by others.
