The sound comes from Microsoft Windows 10, released in 2015, where a short chime alerted users to incoming messages, mail and system notifications. As the operating system became widespread, the tone became part of everyday computer use, so listeners recognise it immediately even outside a desktop context. Shortened versions began circulating on soundboards and in video edits, where creators could drop the alert without the longer system sound. It remains popular because it is brief, clean and instantly readable as a notification.
