Sonic CD, released in 1993 for the Sega CD, made time travel central to its gameplay, letting Sonic visit the past, present and future of each zone to change its outcome. The warp sound became closely linked with that mechanic and with the game's distinctive, colourful take on the Sonic series. As retro gaming clips, speedrun highlights and nostalgic edits spread online, the short effect was lifted onto soundboards and reused far beyond the original game. It endures because it is instantly recognisable to Sonic fans and instantly readable to everyone else as a jump through time.
