Steam defined the modern video game industry

Gather'round, children, and let me tell you a story about the old bugaboo we used to call DRM. Digital Rights Management was the beast under every gamer's bed in the mid-2000s, an invisible bit of software baked into game discs that dictated and tracked player behavior under the guise of preventing piracy. DRM software, like SecuROM, limited the times a game could be downloaded and forced players to regularly connect to the internet for authentication checks, at a time when less than half of American adults had reliable broadband connections. DRM features soured the releases of BioShock, Mass Effect and Spore, and by 2010, anti-piracy software had rendered Assassin's Creed 2 and Splinter-Cell: Conviction unplayable. When Microsoft attempted to release the Xbox One with always-on DRM features in 2013, intense vitriol from fans forced the company to reverse its plans at the 11th hour.
