The original PlayStation, released in Japan on December 3, 1994, was the first of the ubiquitous PlayStation series of console and hand-held game devices. It has included successor consoles and upgrades including the Net Yaroze (a special black PlayStation with tools and instructions to program PlayStation games and applications), "PS one" (a smaller version of the original) and the PocketStation (a handheld which enhances PlayStation games and also acts as a memory card). It was part of the fifth generation of video game consoles competing against the Sega Saturn and the Nintendo 64. By December 2003, the PlayStation and PS one had shipped a combined total of 102.49 million units, eventually becoming the first video game console to sell 120 million units.
Released in 2000, 15 months after the Dreamcast and a year before its other competitors, the Xbox and the Nintendo GameCube, the PlayStation 2 is part of the sixth generation of video game consoles, and is backwards-compatible with most original PlayStation games. Like its predecessor, it has received a slimmer redesign. It is the most successful home console in the world, having sold over 155 million units as of December 28, 2012. On November 29, 2005, the PS2 became the fastest game console to reach 100 million units shipped, accomplishing the feat within 5 years and 9 months from its launch. This achievement occurred faster than its predecessor, the PlayStation, which took "9 years and 6 months since launch" to reach the same figure. PlayStation 2 shipments in Japan ended on December 28, 2012. The Guardian reported on January 4, 2013 that PS2 production had ended worldwide, but studies showed that many people all around the world still own one even if it is no longer in use. PlayStation 2 has been ranked as the best selling console of all time as of 2015.
Released on November 17, 2006 in North America, the PlayStation 3 is a seventh generation game console from Sony. It competes with the Microsoft Xbox 360 and the Nintendo Wii.

The console also incorporates a Blu-ray Disc player and features high-definition resolution. The PS3 was originally offered with either a 20 GB or 60 GB hard drive, but over the years its capacity increased in increments available up to 500 GB. The PlayStation 3 has sold over 80 million consoles worldwide as of November 2013.
