Neopets is an online virtual pet game. The site was opened to the public on November 15, 1999, by Adam Powell and Donna Williams, and a majority interest was bought by Doug Dohring soon after being created. It is currently owned by Viacom after a business transaction valued at $160 million.

The game allows users to create and take care of one to four of 54 species collectively called Neopets, caring for and feeding them in the worlds of Neopia, using Neopoints (NP), the currency of the game. Neopoints are earned through playing games or won through a diverse array of contests and activities on the site. In addition, there are discussion boards, plots, and various sets of items and other things to collect. Its style contains quirks like an abundance of popular culture references. Beyond the website, there is a variety of merchandise, such as two video games, Neopets: The Darkest Faerie, Neopets: Petpet Adventures: The Wand of Wishing and a trading card game. The site has sparked many controversies such as those surrounding the existence of gambling-themed games, the extensive use of immersive advertising, and the Scientology beliefs of the CEO, Doug Dohring.
