Microsoft introduced Windows XP Media Center Edition in 2002 as a version of Windows XP built for home theater PCs, combining television, music, photos and recorded video in a ten-foot interface designed to be used from a sofa. Its startup sound became familiar to owners of early media center computers from manufacturers such as HP and Dell. As those machines disappeared, the chime survived in retro computing videos, operating system showcases and nostalgia edits, where it now works as an instant audio cue for the early 2000s and the first era of the PC in the living room.
