In 1999, GameSpy received angel investment funding from entrepreneur David Berkus. The company released MP3Spy.com (later renamed RadioSpy.com), a software browser allowing people to browse and connect to online radio feeds, such as those using Nullsoft's ShoutCast. GameSpy received $3 million in additional funding from the Yucaipa Companies, an investment group headed by Hollywood agent Michael Ovitz and Southern California supermarket billionaire Ronald Burkle. The expanding of the company's websites included the games portal, GameSpy.com, created in October 1999; the Planet Network (also known as the GameSpy Network), a collection of "Planet" websites devoted to popular video games (such as Planet Quake, Planet Half-Life and Planet Unreal) as well as the genre-related websites, 3DActionPlanet, RPGPlanet, SportPlanet and StrategyPlanet; ForumPlanet, the network's extensive message board system; and FilePlanet, which was one of the largest video game file download sites. It also included platform-specific sites (e.g., Planet PS2, Planet Xbox, Planet Nintendo and Planet Dreamcast), but these were consolidated into GameSpy.com; only Classic Gaming remains separate. ForumPlanet and FilePlanet were services offered by GameSpy, and were not part of the Planet Network. In 2000, GameSpy received additional investment funding from the Ziff Davis publishing division ZDNet.com and from Guillemot Corporation. GameSpy shut down its RadioSpy division, backing away from the online music market which was dominated by peer-to-peer applications such as Napster and Gnutella. In 2001, GameSpy's corporate technology business grew to include software development kits and middleware for video game consoles, such as Sony's PlayStation 2, Sega's Dreamcast and Microsoft's Xbox. In March 2007, IGN and GameSpy Industries merged, and was briefly known as IGN/GameSpy before formalizing their corporate name as IGN Entertainment. Also in 2000, GameSpy turned GameSpy3D into GameSpy Arcade and purchased RogerWilco, MPlayer.com and various assets from HearMe; the MPlayer service was shut down and the RogerWilco technology is improved and incorporated into GameSpy Arcade. GameSpy Arcade was the company's flagship matchmaking software, allowing users to find servers for different online video games (whether they be free or purchased) and connect the user to game servers of that game. GameSpy also published the Roger Wilco voice chat software, primarily meant for communication and co-ordination in team-oriented games, where users join a server to chat with other users on the server using voice communication. This software rivaled the other major voice chat software Ventrilo and Teamspeak. The company's "Powered by GameSpy" technology enabled online functionality in over 300 PC
