The History of Tux the Linux Penguin
In the beginning, sometime in early 1996, several people were talking on the linux-kernel mailing list about a suitable logo/mascot for Linux. Of the many, many suggestions, many involved parodies of other operating system logo's - or were strong, noble beasts such as Sharks or Eagles.
At some point, Linus Torvalds casually mentioned that he was rather fond of Penguins - which rather stopped the debate in its tracks.
Tux made it into Time Magazine in August 2002 in an article by Chris Taylor entitled "The Little Penguin That Could".
