AOL had 30M dial-up subscribers — and the broadband revolution made them irrelevant

AOL (America Online) was the dominant internet service provider in the late 1990s and early 2000s, with over 30 million dial-up subscribers at its peak in 2002. AOL's 'You've Got Mail' notification was the sound of the internet for a generation.

But AOL's business model was built on dial-up access, which charged by the hour or by a monthly subscription for slow, phone-line-based internet. When broadband (cable and DSL) became widely available, offering always-on, high-speed connections, dial-up became obsolete almost overnight.

AOL attempted to transition to broadband and content, but the transition was too slow and the company's culture was too tied to the dial-up subscription model. AOL's subscriber base collapsed from 30 million to under 2 million over the following decade. The case illustrated how a business model built on a specific technology (dial-up) is vulnerable to the next technology (broadband), and how the revenue from the old technology can delay the transition to the new one.
