Dial up internet access dominated homes in the 1990s and early 2000s, using regular phone lines and analogue modems that literally called an internet provider. The beeps and screeches heard here are the modem handshake, the audible negotiation that set speed and protocol before any page could load. As broadband replaced dial up, the sound survived online as shorthand for obsolete technology. It is now shared on soundboards and reused in memes about slow WiFi, old computers and the early internet generations remember waiting through.
