The PlayStation Network is Sony's free online multiplayer gaming and digital media service for the PlayStation 3, PSP, and PS Vita. The service started in 2006, and currently has over 77 million registered accounts. On April 19, 2011, the PlayStation Network was the target of a massive hack, as the personal information of millions of users was stolen. The service went down for nearly a month before coming back online in the US.
PlayStation Network, often abbreviated as PSN, is an online multiplayer gaming and digital media delivery service provided/run by Sony Computer Entertainment for use with the PlayStation 3, PlayStation Portable, and PlayStation Vita video game consoles. The PlayStation Network is the video game portion of the Sony Entertainment Network. Sony's second console, the PlayStation 2, had a limited number of online features in select games via its online network. It required a Network Adaptor, which was available as an add-on for original models, and integrated into the hardware on slimline models. However, Sony provided no unified online service for the system, so support for network features was specific to each game and there was no interoperability of cross-game presence. In March 2006, Sony announced the online network for its upcoming PlayStation 3 system at the 2006 PlayStation Business Briefing meeting in Tokyo, Japan, tentatively named 'PlayStation Network Platform'.
