When Valve launched Steam Direct in June 2017 it marked a huge shift in the storefront's identity. Before Direct, Valve manually decided what did and did not release on Steam, or else it used initiatives like Steam Greenlight to have users decide what games would or would not enjoy placement.
Before June 2017, the amount of games that shipped on Steam per month had only once exceeded 500 (518, in December 2016). Since February 2025, the amount of games shipping on Steam per month has never dropped beneath 1500.
