The Trojan Room coffee pot was a coffee machine located in the Computer Laboratory of the University of Cambridge, England. Created in 1991 by Quentin Stafford-Fraser and Paul Jardetzky, it was migrated from their laboratory network to the web in 1993, becoming the world's first webcam.
To save people working in the building the disappointment of finding the coffee machine empty after making the trip to the room, a camera was set up providing a live picture of the coffee pot to all desktop computers on the office network. After the camera was connected to the Internet a few years later, the coffee pot gained international renown as a feature of the fledgling World Wide Web, until being retired in 2001. [1] [2]
The 128×128 px greyscale camera was connected to the laboratory's local network through a video capture card fitted on an Acorn Archimedes computer. Researcher Quentin Stafford-Fraser wrote the client software, dubbed XCoffee and employing the X Window System protocol, while his colleague Paul Jardetzky wrote the server program. [3]
In 1993, web browsers gained the ability to display images, [4] and it soon became clear that this would be an easier way to make the picture available to users. The camera was connected to the Internet and the live picture became available via HTTP in November of the same year, by computer scientists Daniel Gordon and Martyn Johnson. It therefore became visible worldwide and grew into a popular landmark of the early web.
Following the laboratory's move to its current premises, the camera was eventually switched off, at 09:54 UTC on 22 August 2001. Coverage of the shutdown included front-page mentions in The Times and The Washington Post , as well as articles in The Guardian and Wired . [5]
The last of the four or five coffee machines seen online, a Krups, was auctioned on eBay for £ 3,350 to the German news website Der Spiegel . The pot was later refurbished pro bono by Krups employees, and was switched on again in the magazine's editorial office. [6] Since the summer of 2016, the coffee maker is on permanent loan to the Heinz Nixdorf MuseumsForum in Paderborn. [7]
Spoofs of the Trojan Room coffee machine ranged from the Hyper Text Coffee Pot Control Protocol, a 1998 April Fools' Day specification for a communication protocol, to the 2002 video game Hitman 2: Silent Assassin , in which the player can destroy a "coffee camera" in a kitchen as a distraction. The coffee pot was also mentioned in the BBC Radio 4 drama The Archers on 24 February 2005. [6]
A webcam is a video camera which is designed to record or stream to a computer or computer network. They are primarily used in video telephony, live streaming and social media, and security. Webcams can be built-in computer hardware or peripheral devices, and are commonly connected to a device using USB or wireless protocols.
The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first computer networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the Advanced Research Projects Agency of the United States Department of Defense.
VNC is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse input from one computer to another, relaying the graphical-screen updates, over a network. Popular uses for this technology include remote technical support and accessing files on one's work computer from one's home computer, or vice versa.
The Department of Computer Science and Technology, formerly the Computer Laboratory, is the computer science department of the University of Cambridge. As of 2023 it employed 56 faculty members, 45 support staff, 105 research staff, and about 205 research students. The current Head of Department is Professor Alastair Beresford.
A webcast is a media presentation distributed over the Internet using streaming media technology to distribute a single content source to many simultaneous listeners/viewers. A webcast may either be distributed live or on demand. Essentially, webcasting is "broadcasting" over the Internet.
In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall. This technique is most commonly used to make services on a host residing on a protected or masqueraded (internal) network available to hosts on the opposite side of the gateway, by remapping the destination IP address and port number of the communication to an internal host.
PaderbornUniversity is one of the fourteen public research universities in the state of North Rhine-Westphalia in Germany. It was founded in 1972 and 20,308 students were enrolled at the university in the winter semester 2016/2017. It offers 62 different degree programmes.
James Quentin Stafford-Fraser is a computer scientist and entrepreneur based in Cambridge, England. He was one of the team that created the first webcam, the Trojan room coffee pot. Quentin pointed a camera at the coffee pot and wrote the XCoffee client program which allowed the image of the pot to be displayed on a workstation screen. When web browsers gained the ability to display images, the system was modified to make the coffee pot images available over HTTP and thus became the first webcam.
The Hyper Text Coffee Pot Control Protocol (HTCPCP) is a facetious communication protocol for controlling, monitoring, and diagnosing coffee pots. It is specified in RFC 2324, published on 1 April 1998 as an April Fools' Day RFC, as part of an April Fools prank. An extension, HTCPCP-TEA, was published as RFC 7168 on 1 April 2014 to support brewing teas, also as an April Fools' Day RFC in error 418.
Videotelephony is the use of audio and video for simultaneous two-way communication. Today, videotelephony is widespread. There are many terms to refer to videotelephony. Videophones are standalone devices for video calling. In the present day, devices like smartphones and computers are capable of video calling, reducing the demand for separate videophones. Videoconferencing implies group communication. Videoconferencing is used in telepresence, whose goal is to create the illusion that remote participants are in the same room.
Nixdorf Computer AG was a West German computer company founded by Heinz Nixdorf in 1952. Headquartered in Paderborn, Germany, it became the fourth largest computer company in Europe, and a worldwide specialist in banking and point-of-sale systems.
A computer network is a set of computers sharing resources located on or provided by network nodes. Computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.

In computing, the term remote desktop refers to a software- or operating system feature that allows a personal computer's desktop environment to be run remotely from one system, while being displayed on a separate client device. Remote desktop applications have varying features. Some allow attaching to an existing user's session and "remote controlling", either displaying the remote control session or blanking the screen. Taking over a desktop remotely is a form of remote administration.
Jennifer Kaye Ringley is an Internet personality and former lifecaster. She is widely regarded as the first camgirl. She is known for creating the popular website JenniCam. Previously, live webcams transmitted static shots from cameras aimed through windows or at coffee pots. Ringley's innovation was simply to allow others to view her daily activities. She was the first web-based "lifecaster". She retired from lifecasting at the end of 2003.

The Heinz Nixdorf MuseumsForum (HNF) in Paderborn, Germany, is a computer museum named after the Paderborn computer pioneer and entrepreneur Heinz Nixdorf.
FogCam is the longest-running webcam in the world, barring maintenance breaks and camera replacements. In 1994, two students Jeff Schwartz and Dan Wong set up the webcam at San Francisco State University. It was nearly shut down in 2019 as the creators said they faced difficulties in maintaining the webcam. Following public outcry, the university agreed to take over ownership and continue its maintenance.
