Google Logo By Kids

In 1998 Sergey Brin created a computerised version of the Google letters using the free graphics program GIMP. The exclamation mark was added, mimicking the Yahoo! logo. "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."
In 2010, the Google logo received its first major and permanent overhaul since 1999. The new logo was first tested in November 2009, and was officially launched on May 6, 2010. It utilises an identical typeface and colors to the previous logo, but features a much more subtle shadow and uses a different shading style.
