PSN is the online network used by Sony for the PlayStation game consoles. In recent times, the network was integrated into Sony’s larger network which had its domain changed to the Sony Entertainment Network. The functionality remains the same, as well as branding and terminology.
PlayStation network first launched to the wider gaming audience with the PlayStation 3. This console was the first to allow gamers to purchase digital games from an online store and also allowed gamers to play multiplayer games over a network. PSN was what facilitated this.
The network has expanded and improved significantly over the years and has become a flagship online gaming platform that connects gamers all around the world.
