Manufactured by Sony Computer Entertainment, the PlayStation Vita is an eighth generation handheld video game console and the successor to the PlayStation Portable. It was released in Japan in December 2011 and North America in February 2012. The Vita features a five-inch OLED touch screen, two analog sticks, a directional pad and two shoulder buttons. The device also contains a rear touchpad, a front and rear camera, microphone and motion sensors. Games are stored on the PlayStation Vita card, a flash memory card similar to those used by the Nintendo DS. The Vita is backwards compatible with PlayStation Portable games downloaded from the PlayStation Network. Due to the PSP's use of Universal Media Discs, physical games are not compatible. The Vita launched with approximately 30 games, some available through physical media and others digitally downloaded from the PlayStation Store.
