Neopets (originally NeoPets) is a virtual pet website launched by Adam Powell and Donna Williams on 15 November 1999.[1] Two years after the web site was launched, Adam Powell and Donna Williams sold a majority share to a consortium of investors led by Doug Dohring. On 20 June 2005, Viacom bought Neopets, Inc. for US$160 million.[2]

Neopets is a website dedicated to the creation of virtual pets that inhabit the virtual world of Neopia. Visitors can create an account and take care of up to four virtual pets, buying them food, toys, clothes, and other accessories using the virtual currency called Neopoints, and Neocash. Neopoints can be earned through playing games, investing in the game's stock market, trading, and winning contests, while Neocash must be purchased with money, although certain events may allow users to earn Neocash for free. Users can explore the world of Neopia with their Neopets and interact with each other through the Neoboards, NeoMail, guilds, and Key Quest.

Neopets also operates a pay-to-play version known as Neopets Premium, which offers additional features and benefits for a monthly fee of US$7.99. Neopets, Inc. produces and sells a wide variety of Neopets merchandise, such as plushies, stickers, notebooks, three video games and a trading card game.
