Neopets
When Neopets debuted in 1999, it quickly became a staple of browser-based, free-to-play games. The online world of Neopia allows its players to explore various lands, care for pets, and engage in a robust social component, complete with opportunities to chat with other players and form guilds. Neopets also showcased the potential of the Internet for gaming and served as a testing ground for cyber safety mechanisms and immersive advertising. At its peak in 2005, Neopets had 25 million active users, and it continues to be popular more than two decades later.
