PlayStation 2

Launched in the year 2000, Sony's second home console, the PlayStation 2, had rudimentary 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 service for the system, so support for network features was specific to each game and third-party server, and there was no interoperability of cross-game presence.
