Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network (PSTN) to establish a connection to an Internet service provider (ISP) by dialing a telephone number on a conventional telephone line. Dial-up connections use modems to decode audio signals into data to send to a router or computer, and to encode signals from the latter two devices to send to another modem at the ISP.

Dial-up internet reached its peak popularity during the dot-com bubble with the likes of ISPs such as Sprint, EarthLink, MSN Dial-up, NetZero, Prodigy, and America Online (more commonly known as AOL). This was in large part because broadband internet did not become widely used until well into the 2000s. Since then, most dial-up access has been replaced by broadband.
