Picture this: You're a computer researcher at Cambridge University in 1991. You desperately need coffee. You walk three flights of stairs to the Trojan Room where the communal coffee pot lives. And it's empty. Again. This happened so often that two researchers decided to solve the problem with technology.

Quentin Stafford-Fraser and Paul Jardetzky created the world's first webcam for one simple purpose: monitoring a coffee pot. They rigged up a camera to capture 128×128 pixel greyscale images of the Krups coffee maker and broadcast them across the lab's local network. Now anyone could check if the pot was full before making the trek.

From Office Tool to Internet Legend

For two years, this was purely internal—a quality-of-life improvement for caffeine-dependent researchers. Then in November 1993, Daniel Gordon and Martyn Johnson connected the camera to the Internet. Suddenly, anyone in the world could watch a coffee pot at Cambridge.

The timing was perfect. The World Wide Web was just beginning to explode. People were hungry for examples of what the internet could do, and this quirky application captured imaginations worldwide. Here was cutting-edge technology devoted to the most mundane task imaginable.

Global Coffee Monitoring

The Trojan Room coffee pot became an unlikely internet celebrity. Thousands of people would check in daily to see if Cambridge researchers had brewed a fresh pot. It ran continuously for nearly a decade, becoming one of the internet's earliest "always-on" attractions.

When the webcam was finally switched off on August 22, 2001 at 9:54 UTC, it felt like the end of an era. The coffee pot itself was auctioned on eBay, fetching £3,350 from German news outlet Spiegel Online. Today it rests in the Heinz Nixdorf MuseumsForum in Germany—a monument to human ingenuity applied to very human problems.

The legacy? Every video call, security camera, and live stream traces back to researchers who just wanted to know if there was coffee ready. Sometimes the most revolutionary technology comes from solving the smallest annoyances.
