The PlayStation 3 is a home video game console developed by Sony Computer Entertainment. It is the successor to PlayStation 2, and is part of the PlayStation brand of consoles. The console was the first PlayStation to integrate social gaming services, including being the first to introduce Sony's social gaming service, PlayStation Network and its remote connectivity with PlayStation Portable and PlayStation Vita being able to remote control the console from the devices. The system had a slow start in the market but managed to recover, particularly after the introduction of the Slim model.
