MSN TV 2 was the set-top box that brought the MSN TV internet service to a television, so its interface sounds were heard in living rooms rather than at a computer desk. The connecting sound marked the moment the box went online, and it has since survived as a piece of retro tech audio shared on soundboards and in short nostalgia edits. It is still used because that brief electronic sequence instantly signals an older, slower internet, making it a useful shorthand for early home browsing and vintage technology humour.
