Steam was first created as a distribution platform for PC video games way back in 2003. While selling video games remains its primary focus, Steam has grown into a platform where you can interact with other players, live stream, or even create and upload your own games.
Some of the most popular PC games in the world can be found on Steam. This includes the likes of Apex Legends, PUBG: Battlegrounds, Lost Ark, Counter-Strike: Global Offensive, Call of Duty: Warzone, the FIFA franchise, and loads more.
