Guru is an animation studio.
2000 (Website only)
Before Guru had an actual logo, they used basic blue HTML text on their website as a placeholder.
Sometime between October 2000 and February 2001, Guru modified the text on their website to be more stylized, however, it is still just HTML text instead of an actual image file.
In 2002 (or possibly late 2001) the HTML text was replaced with a .gif banner.
