Valve introduced its logo sting in its early PC games in the late 1990s, showing a man with a valve in his head as a short musical theme played. The version tied to Team Fortress 2, released in 2007, kept that ritual for a new generation of players launching the game through Steam. As clips and parodies spread on video platforms, the opening notes became shorthand for PC gaming itself, and fans still use the longer TF2 cut when they want the complete build rather than a shortened sting.
