La revista Wired publica esta pequeña galería con la evolución en la creación del logo de Google. Citando la introducción:

In just a few short years, Google’s logo has become as recognizable as Nike’s swoosh and NBC’s peacock. Ruth Kedar, the graphic designer who developed the now-famous logo, shows the iterations that led to the instantly recognizable primary colors and Catull typeface that define the Google brand. Kedar met Google co-founders Sergey Brin and Larry Page through a mutual friend nine years ago at Stanford University, where she was an assistant professor. Page and Brin, who were having trouble coming up with a logo for their soon-to-launch search engine, asked Kedar to come up with some prototypes. "I had no idea at the time that Google would become as ubiquitous as it is today, or that their success would be of such magnitude," Kedar says.
