In 1998, Sergey Brin created a computerized version of the Google letters using the free graphics program GIMP. The exclamation mark was added, mimicking the Yahoo! logo.[4] "There were a lot of different color iterations", says Ruth Kedar, the graphic designer who developed the now-famous logo. "We ended up with the primary colors, but instead of having the pattern go in order, we put a secondary color on the L, which brought back the idea that Google doesn't follow the rules."[5]
