Club Penguin actually started sometime in August of 2005 for Beta Testing. It was opened to the public on October 24rd, 2005. There is a long history of Club Penguin. The first related game was made in 2000 by Rocketsnail Games, and it was called "Experimental Penguins". After that, came Penguin Chat (which was actually Penguin Chat 2), a game still online at http://www.penguinchat.com/ (caution: adult material is sometimes said). Then, Penguin Chat 3 came, which was inspired the creators to make Club Penguin.
