How 'PUBG' became this year's biggest video game

Nearly three years ago, Brendan Greene was living on welfare in his home country of Ireland. PlayerUnknown's Battlegrounds is a title few non-video game diehards have ever heard of. That's partly because Greene and game developer Bluehole Studio have not marketed the game. Instead, a combination of viral buzz through streaming services like Twitch and a novel spin on the shooter genre propelled PUBG (pronounced "pub-gee") to popularity on par with Call of Duty, with massive production and advertising budgets. This week, having thrived on PC, PUBG will enjoy a new wave of players by making its debut on Microsoft's Xbox One.
