What the webcam has to do with coffee

What happens when a couple of students want to know whether the coffee pot’s full, but are too lazy to check for themselves? That’s right, the webcam’s born!
These days, we take computer peripherals such as keyboards, mice, speakers and webcams for granted. Yet, there’s a interesting story behind webcams in particular, that, if anything tells us laziness spurs inventions.
Long before the days of working from home and video calls, the PC camera was originally invented for a completely different purpose. Let’s take a look back at how it all began:
Coffee for students
It’s 1991 and Paul Jardetzky and Quentin Stafford-Fraser are studying at the University of Cambridge. As well as having a shared interest in coding, the two also share a love of fresh coffee. The problem? The communal coffee machine in the Trojan Room of the old computer lab is located at the other end of the campus.
As if the long journey isn’t bad enough, in the worst case, they get there to find an empty coffee pot. The solution? The two budding software engineers set up a small, digital black-and-white camera in the Trojan Room with a view of the machine. They add some home-made hardware and software, et voilà: the first webcam is born.
From this day on, all students at the University of Cambridge can access the camera via the local network and check the coffee level before they embark on the long journey.
However, the camera wasn’t actually connected to the World Wide Web – as the name suggests – until two years later by Daniel Gordon and Martyn Johnson. From November 1993, the whole world could stare into the coffee pot.
On the other hand, webcams can of course be found at every tourist hotspot around the globe.
In a way, the coffee pot from Cambridge could even be considered the great-grandfather of all Twitch streamers, who now reach an audience of millions every day. Or simply as a curious piece of internet culture and the birth of the webcam.
