Overview
Steam began as Valve’s solution for updating Counter-Strike. It became PC gaming’s dominant distribution platform, fundamentally changing how games are sold, updated, and played. Steam’s success enabled the indie revolution, introduced seasonal sales culture, and made Valve one of gaming’s most valuable private companies—all while remaining controversial for its market dominance and curation policies.

Legacy
Steam proved digital distribution could replace retail for games. Its success funded Valve’s transition from developer to platform owner. The company’s hands-off approach created both the indie revolution and the curation crisis. Love it or resent it, Steam defined how PC games are bought and played in the 21st century.
