Club Penguin was a massively multiplayer online game (MMO) that ran from 2005 to 2017. The game featured a virtual world that included a wide range of online games and activities. It was created by New Horizon Interactive (now known as Disney Canada Inc.). Players used cartoon penguin avatars and played in an Antarctic-themed open world. After beta-testing, Club Penguin was made available to the general public on October 24, 2005. It expanded into a large online community, such that by late 2007, Club Penguin reported that there were more than 30 million user accounts. In July 2013, Club Penguin had more than 200 million registered user accounts.
While free memberships were available, revenue was predominantly raised through paid memberships, which allowed players to access a range of additional features, such as the ability to purchase virtual clothing, furniture, and in-game pets called "Puffles" for their penguins through the usage of in-game currency. The success of Club Penguin led to New Horizon being purchased by the Walt Disney Company in August 2007 for the sum of 350 million U.S. dollars, with an additional 350 million dollars in bonuses if specific targets were met by 2009.
