The short version of the dial up to broadband history is this: in the US, home broadband overtook dial-up between April 2004 and March 2005, according to Pew Research Center surveys, and dial-up fell to a few percent of adults by the early 2010s. What changed was not only speed. Broadband was always on, it left the phone line free, and it made video, big downloads and constant messaging normal. The last symbolic step came on September 30, 2025, when AOL discontinued its dial-up internet service.
Below is how dial-up actually worked, why it made that noise, what the switch cost people, and the survey numbers that show when the crossover happened.
How dial-up worked, and why it screamed
Dial-up used the ordinary telephone network, the same copper line and the same exchanges as a voice call. Your computer’s modem literally phoned a number belonging to your internet provider. As Wikipedia’s article on dial-up access (read September 27, 2026) puts it, a modem “would take the digital data from a computer, modulate it into an audio signal and send it to a receiving modem.” The word modem is short for modulator-demodulator.
That explains the famous sound. The phone network was designed to carry voices, so the two modems had to talk to each other in sound. The screeching, hissing and chirping at the start of every session was the two machines testing the line and agreeing on how fast they could safely communicate. Most modems played that negotiation through a small speaker so you could hear whether the call had connected, which is why a whole generation can still hum it.
It also explains the biggest household complaint: while someone was online, the phone line was busy. Nobody could call in, and picking up an extension could knock the connection off.
Why dial-up topped out at 56k
The late dial-up standards, V.90 and V.92, reached a theoretical maximum of 56 kilobits per second. Wikipedia’s dial-up article explains the ceiling: the digital channel behind a phone call carries 64 kbit/s and reserves 8 kbit/s for signaling, so “a 56 kbit/s connection is the highest that will ever be possible with analog phone lines.” The same article notes that real-world speeds typically landed around 40 to 50 kbit/s.
ISDN, a digital phone-line service sold as an upgrade, offered 64 to 128 kbit/s according to the same source. It was faster but never became a mass consumer product in the way broadband did.
To put 56k in context: it was measured in kilobits. Modern home connections are measured in megabits or gigabits, thousands of times more. A single song or a short video clip could take many minutes on a good dial-up day.
Dial up to broadband history: the US crossover, by the numbers
The clearest record of the switch comes from the Pew Research Center, which asked American adults the same question for fifteen years. Pew’s “Broadband vs. Dial-up Adoption Over Time” chart (read September 27, 2026) shows the share of US adults using each type of home connection:
| Pew survey date | Dial-up at home | Broadband at home |
|---|---|---|
| June 2000 | 34% | 3% |
| April 2001 | 41% | 6% |
| March 2003 | 37% | 16% |
| April 2004 | 30% | 24% |
| March 2005 | 28% | 33% |
| March 2006 | 23% | 42% |
| April 2008 | 10% | 55% |
| May 2010 | 5% | 64% |
| September 2013 | 2% | 70% |
Read across the rows and the story is plain. In Pew’s data, dial-up peaked in 2001. Broadband passed it somewhere between the April 2004 and March 2005 surveys. By 2010 dial-up was down to 5% of adults.
One note on the sources: Pew’s own May 2006 report, “Home Broadband Adoption 2006” by John B. Horrigan, gives 30% of adults with home broadband in March 2005, while the later chart shows 33% for the same month. Both figures come from Pew and the chart does not explain the difference, so the safest reading is that the crossover happened in late 2004 or early 2005 rather than in one specific month.
What broadband actually changed
Speed is the obvious answer, but it was not the only change, and arguably not the most important one.
Always on
Dial-up was an event. You decided to go online, waited for the connection, did what you needed and hung up, partly because the phone line was tied up. Broadband simply stayed connected. That shift created the idea of being online all day, which is the precondition for buddy lists, notifications and later social feeds.
It is no coincidence that the golden age of desktop messengers ran alongside the broadband rollout. Our histories of AIM, which ended on December 15, 2017, and of MSN Messenger’s two migrations both sit inside this always-on shift.
The phone line came back
DSL, one of the two main early broadband technologies, used the same copper phone wires as dial-up but carried data in a way that did not block voice calls. Cable broadband used the television cable instead. Either way, the family phone worked again while someone was online.
Heavier content became reasonable
Photos, music files and eventually video only made sense for most households once broadband was common. Pew’s April 18, 2004 report, “Broadband Adoption at Home Grows Strongly in Winter Months of 2003 & 2004,” found that “nearly 60% of home broadband users say that impatience with dial-up connections or a desire to download files faster is the reason they switched to broadband.” The web platforms that defined the late 2000s, many covered in our guide to the platforms that shaped the internet, then vanished, assumed a reader on a fast connection.
What it cost
The same 2004 Pew report said price “plays a relatively minor role” in the decision to switch, but broadband was clearly the pricier option. Pew’s May 2006 report, read September 27, 2026, gives average monthly bills reported in December 2005:
- Dial-up: $18 a month
- Broadband overall: $36 a month
- DSL: $32 a month
- Cable modem: $41 a month
So broadband cost roughly double what dial-up did at the time, in 2005 dollars. The same report found that “a significant part of the increase is tied to internet newcomers who have bypassed dial-up connections and gone straight to high-speed connections.” In other words, by the mid 2000s many people never used dial-up at all; they started on broadband.
Why dial-up hung on so long
Dial-up did not vanish when broadband took the lead. It needed only a phone line, so it kept working in places where no cable or DSL service reached, and for people who went online rarely enough that a higher bill made no sense.
Wikipedia’s dial-up article puts dial-up at around 40% of US households in the early 2000s, 6% in 2010, 3% in 2013 and 0.3% by 2017, and estimates that 163,000 to 175,000 Americans still used it before AOL’s shutdown. Those figures are measured differently from Pew’s, which count adults rather than households, so the two series should not be mixed; the Pew chart is the more direct record for the 2000 to 2015 period.
The last dial tone: AOL shuts off dial-up
AOL was the name most Americans associated with dial-up. On August 11, 2025, ABC News reported (read September 27, 2026) that AOL had posted a notice saying it “routinely evaluates its products and services” and would discontinue dial-up internet on September 30, 2025, along with its dialer software. ABC noted the change did not affect other AOL plan benefits. Wikipedia’s dial-up article puts the service’s run at 34 years.
That date is the practical end of the dial up to broadband history. The technology is not physically impossible to use today, but the brand that brought many Americans online through a modem no longer offers it.
FAQ
When did broadband overtake dial-up in the US?
Pew Research Center surveys show dial-up at 30% and broadband at 24% of US adults in April 2004, then dial-up at 28% and broadband at 33% in March 2005. The crossover happened between those two surveys.
Why did dial-up internet make that noise?
The phone network carried sound, so modems communicated by turning data into audio. The screeching at the start of each session was the two modems testing the line and agreeing on a speed, and most modems played it through a speaker so users could hear the connection form.
How fast was dial-up compared with broadband?
The last dial-up standards had a theoretical maximum of 56 kbit/s, with real speeds usually around 40 to 50 kbit/s, according to Wikipedia’s dial-up article. Early broadband was many times faster, and modern connections are measured in megabits or gigabits per second.
Is dial-up internet still available?
AOL discontinued its dial-up service on September 30, 2025, as reported by ABC News. Dial-up remains technically possible over a phone line, but the best-known consumer service is gone.
How much did broadband cost in the 2000s?
Pew’s 2006 report found US home broadband users paid about $36 a month on average in December 2005, compared with about $18 for dial-up.
