The Xbox 360 startup sound comes from the Xbox 360 console boot sequence, first associated with the system's 2005 launch era. It became familiar through years of everyday use as players powered on the console, signed in, and loaded games. Online, the audio spread through nostalgia compilations, dashboard recreations, and gaming edits focused on the late 2000s and early 2010s. It still gets used because the chime is short, clean, and instantly tied to a specific generation of console gaming.
