Club Penguin

Club Penguin is a  massively multiplayer online game (MMO) involving a virtual world containing a range of online games and activities, created by New Horizon Interactive (now known as Disney Canada Inc.). Players use cartoon penguin-avatars and play in a winter-set virtual world. After beta-testing, Club Penguin was made available to the general public on October 24, 2005 and has since expanded into a large online community —growing to the extent that by late 2007, it was claimed that Club Penguin had over 30 million user accounts. As of July 2013, Club Penguin has over 200 million registered user accounts.
