Sony's first foray into the video game market, the PlayStation (codenamed PSX during development, now known as PSone), was initially designed as an add-on for Nintendo's Super Nintendo Entertainment System (Super Famicom) video game console as an answer to Sega's Sega CD. When the prospect of releasing the system as an add-on dissolved, Sony transformed it into the standalone PlayStation video game console.
Sony's follow-up console, the PlayStation 2 (PS2), currently the world's best-selling console in history, was released in Japan on March 4, 2000 and in North America on October 26, 2000.
The PSP or PlayStation Portable is a handheld game console made by Sony Computer Entertainment; a first foray into the handheld gaming market which was previously dominated by Nintendo. Though it has not had as much as of an impact as the PlayStation home consoles, the PSP is noted as being the most successful competitor to Nintendo's handheld range yet.
The PlayStation is a 32-bitvideo game console first released by Sony Computer Entertainment in Japan on December 3, 1994, with Western releases from September 1995. The PlayStation was the first of the PlayStation series of consoles and handheld game devices. As part of the fifth-generation of gaming, it primarily competed with the Nintendo 64 and the Sega Saturn. In 2000, a re-designed, "slim" version was released, called the PSone, replacing the original grey console, and also being renamed to avoid confusion with its successor, the PlayStation 2. The PlayStation was the first "computer entertainment platform" to ship 100 million units, which it had reached 9 years and 6 months after its initial launch. The last PSone units were sold on Christmas 2004 before it was finally discontinued, for a total of 102 million units shipped since its launch 10 years earlier. Games continued to sell until Sony ceased production of PlayStation games on March 23, 2006; over 11 years after it was released, and just over half a year before the release of the PlayStation 3.
