There are plenty of reasons for this phenomenon, but I won’t try to enumerate it here. Perhaps seeing my collection of "30 Coolest and Funniest Tux Icons" can somehow help explain why Tux is so adored. But first, some brief Tux facts:
The concept of the Linux mascot being a penguin came from Linus Torvalds.
Tux was created by Larry Ewing in 1996 after an initial suggestion made by Alan Cox and further refined by Linus Torvalds on the Linux kernel mailing list.
Linus took his inspiration from a photograph he found on an FTP site, showing a penguin figurine looking strangely like the Creature Comforts characters made by Nick Park. The first person to call the penguin "Tux" was James Hughes, who said that it stood for "(T)orvalds (U)ni(X)". However, many people observe that Tux is also an abbreviation of tuxedo, the outfit which springs to mind when they see a penguin.
