PSP released in Japan on December 12, 2004 and is already a runaway hit, with more than 1.18 million units shipped to date. As a key device for the company, PSP sets a new standard as the first truly integrated portable entertainment system designed to provide consumers with a comprehensive entertainment experience, including games, music, movies, communication, and wireless networking. Featuring graphics rendering capabilities comparable to its sister product, the PlayStation 2 computer entertainment system, PSP brings an unparalleled gaming experience to a portable platform, allowing users to enjoy 3D games, with high-quality, full-motion video, and high-fidelity stereo audio. PSP also allows for digital photo display and supports digital music playback in both MP3 and ATRAC formats.

PSP also comes complete with built-in stereo speakers, exterior headphone connector and diverse input/output connectors such as USB 2.0, and 802.11b (Wi-Fi) wireless LAN, enabling users to connect to the Internet and play online via a wireless network. Up to 16 PSP systems in the vicinity can also be connected to each other directly in ad-hoc mode, allowing for wireless head-to-head competition. In addition, wireless capabilities will allow software and data to be downloaded to a PSP and saved onto a Memory Stick Duo.
