The world’s first webcam was used to monitor a coffee pot. In late 1991, researchers at the University of Cambridge Computer Laboratory pointed a camera at their communal coffee machine so they could check whether it was full or empty without leaving their desks.
The Problem That Started It All
The Computer Laboratory’s coffee pot sat in a room known as the Trojan Room. Members of the “coffee club” worked on different floors of the building, and getting to the pot meant navigating several flights of stairs. The trip was often wasted because late-night researchers in the Trojan Room had already drained it. As Quentin Stafford-Fraser, one of the project’s creators, put it, this disruption to computer science research “obviously caused us some distress.”
So Stafford-Fraser, Paul Jardetzky, and a handful of colleagues did what engineers do: they solved the problem with technology. They pointed a camera at the coffee pot and wrote custom software called XCoffee that displayed the live image on everyone’s computer screen over the lab’s internal network. Before making the trip downstairs, you could glance at a tiny, grainy thumbnail and see whether the pot was worth walking to.
From Local Network to the World Wide Web
For about two years, the coffee pot camera was only visible inside the Cambridge lab network. That changed when the feed was connected to the web, making it accessible to anyone with a browser. The image updated just a few times per minute, far from smooth video, but it was enough. It became one of the earliest examples of a live camera feed on the internet, and curiosity drove traffic from around the world. People who had no interest in the coffee level tuned in simply because they could.
A Decade of Fame
The Trojan Room coffee pot ran as a webcam for nearly a full decade. It became an oddly beloved internet fixture, one of those early-web phenomena that people bookmarked and checked for no practical reason. By the time the camera was finally switched off at 10:54 a.m. on August 22, 2001, thousands of similar feeds had appeared across the internet, showing everything from city streets to bird nests. The humble coffee pot had helped spark an entirely new way of using cameras.
The coffee pot itself went up for auction on eBay after the camera shut down. It attracted 71 bids and sold for £3,350 to the German news magazine Der Spiegel, which promptly put it back into service brewing coffee at its offices.
Why a Coffee Pot Matters to Tech History
The Trojan Room experiment was never meant to be historic. It was a quick hack to avoid a pointless walk. But it demonstrated something powerful: a camera connected to a network could let people monitor the physical world remotely in real time. That idea, almost trivial when applied to a coffee pot, became the foundation for video chat, security cameras, wildlife cams, baby monitors, and the broader concept now called the Internet of Things.
Within a few years of the coffee pot going live, webcams were a consumer product. By the early 2000s, video chatting services began rolling out. Today, most laptops and smartphones ship with built-in cameras as standard hardware. All of it traces a line back to a group of researchers in Cambridge who just wanted to know if there was any coffee left.
