Manual typewriters were the standard writing machines for much of the twentieth century, before electric typewriters and computers replaced them, and their distinctive key and carriage sounds became shorthand for writing itself. As a standalone effect, the typewriter clatter has long been used in films, radio plays and cartoons to signal a busy office, a reporter at work, or a letter being written. Online, short clips like this one are reused in memes, edits and tutorials whenever a creator wants an instantly recognisable, nostalgic writing sound without recording a real machine.
