The creation of the world's first webcam to monitor coffee

The world’s first webcam was installed in 1991 in a room called “Trojan Room” at the University of Cambridge Computer Laboratory to monitor a coffee machine. The main purpose of the system, established by researchers Quentin Stafford-Fraser and Paul Jardetzky, was to prevent employees from unnecessarily going up and down stairs by seeing from their computers whether there was coffee in the pot. The camera initially transmitted several frames of grayscale images per second over the internal network, and in 1993, it connected to the World Wide Web, earning the title of the first camera to broadcast over the internet.

The Purpose of the Trojan Room Coffee Machine

Researchers at the University of Cambridge Computer Laboratory developed this solution because they were tired of going downstairs for coffee only to find an empty pot. Their goal was to prevent time loss and disappointment by only getting up from their desks when there was fresh coffee in the pot.
For this, they installed a camera pointed at the coffee machine, and thanks to a special program they wrote, they displayed the instant status of the pot on their computer screens at a speed of 1-3 frames per second and in grayscale. This simple need for practicality laid the foundation for live image transmission over the internet.
The famous Trojan Room coffee machine at Cambridge University retired after 10 years of continuous broadcasting and then embarked on an international journey.

The Coffee Machine’s Journey

1. Decision to Shut Down (August 22, 2001)

The camera broadcast was terminated due to the relocation of the research laboratory. The last image captured by the camera was the fingers of the scientists pressing the button to shut down the system.

2. Auction and New Owner (2001)

The used Krups brand coffee machine was put up for auction online and was purchased for 3,350 Pounds Sterling by the German news magazine Der Spiegel. Repaired and refurbished free of charge by Krups employees, the machine started brewing coffee again in the magazine’s editorial office.

3. Transition to Museum (2016 – Present)

Since the summer of 2016, the historic coffee machine has been permanently loaned to the Heinz Nixdorf MuseumsForum in Paderborn, Germany, where it is currently on display.

Developments in Live Streaming Technology

The path opened by the Trojan Room coffee machine transformed into a massive live streaming industry within a few decades, with falling hardware costs and increasing internet bandwidth. The development process, spanning from 1 frame per second grayscale images to today’s 4K resolution broadcasts watched by millions simultaneously, passed through certain turning points.

1. First Live Concert Broadcast (1993)

The same year the coffee camera connected to the network, a music group called Severe Tire Damage, composed of engineers from Palo Alto, became the first group to broadcast live over the internet using Mbone (Multicast Backbone) technology. A year later, the Rolling Stones also used the same technology to live stream 20 minutes of one of their concerts over the internet.

2. Commercial Cameras Enter Homes (1994)

Connectix company released the QuickCam, the first commercial webcam, sold for only $100. This device was initially produced only for Macs and could record low-resolution video at 15 fps (15 frames per second) in 16 shades of gray.

3. Foundation of Streaming Technology (1995)

RealNetworks company developed the RealAudio (and later RealVideo) format, which allowed media files to be played simultaneously without waiting for the entire file to download to the computer. This was the first commercially successful application of the modern “streaming” (data flow) logic.

4. The Birth of Lifecasting and Justin.tv (2007)

Justin Kan founded the Justin.tv platform by starting to live stream his own life 24/7 with a camera mounted on his head. This “lifecasting” concept rapidly grew the platform. The platform’s gaming broadcast category became so popular that it spun off in 2011 to form what we know today as Twitch.

5. Mobile Broadcasting Revolution (2015 and Beyond)

With the spread of 4G technology and the development of smartphone cameras, broadcasting moved from computers to pockets. This mobile live streaming boom, which began with Meerkat and Periscope (acquired by Twitter), soon became a core feature of massive platforms like Instagram Live, Facebook Live, and TikTok.

Innovation Born out of Necessity

In the world of engineering and software, the desire to avoid physical effort or repetitive tasks is often the greatest driving force for automation and new inventions. The emergence of the Trojan Room camera was also the result of a practical “laziness” and the pursuit of efficiency.
Researchers working on different floors or corridors would go up and down stairs just to get coffee and often encountered an empty pot. The time loss and disappointment caused by this situation pushed them to use the network technologies at hand instead of moving physically. The reflex to avoid an everyday problem enabled the concept of image transmission over the internet to be proven.
