The tada chime has been part of Microsoft Windows sound schemes since the early 1990s, when a short tada.wav file shipped with Windows 3.1, and it carried through later versions including Windows 7, released in 2009. Windows 7 kept the familiar default scheme that many users heard daily for logons, alerts and system events. Online, the sound survived long after support ended in 2020 because it instantly evokes that era of PCs. It sits alongside other familiar PC cues like the ding sound effect and error sounds that creators mix into desktop parodies.
