Dial up access dominated home internet in the 1990s and early 2000s, and its modem handshake became one of the most recognised sounds of the era. The tones were not decorative, they were two modems testing the phone line and negotiating speed and protocol. As broadband replaced dial up, the recording survived online as a nostalgic meme, reused in videos, edits and soundboards whenever a creator needs a shorthand for slow, outdated or broken internet.
