Steam was launched in 2003 as a platform for updates to Valve's games and became a full-fledged storefront in 2005. Gabe Newell, co-founder of Valve, reached out to Adrian Chmielarz in the early days to feature the game Painkiller on Steam, but Chmielarz was hesitant as they did not hold the rights to the game. Painkiller's Black Edition was eventually released on Steam in 2007. The emergence of digital storefronts like Steam has transformed game development, allowing smaller developers greater access to audiences without the need for traditional publishers. Steam has revolutionized video game distribution, despite challenges like game discoverability, and has become essential to the PC gaming ecosystem.
