Web Cam

Started in 1991, the first such camera, called the CoffeeCam, was pointed at the Trojan room coffee pot in the computer science department of Cambridge University. The camera was finally switched off on August 22, 2001. The final image captured by the camera can still be viewed at its homepage.
The coffee machine was repaired for free by Krups. The oldest webcam, as the technology came to be known, still operating is FogCam at San Francisco State University, which has been running continuously since 1994.
One of the most widely reported-on webcam sites was JenniCam, started in 1996, which allowed internet users to constantly observe the life of its namesake, somewhat like reality TV series Big Brother, launched three years later. More recently, the website Justin.tv has shown a continuous video and audio stream from a mobile camera mounted on the head of the site's star.
Recently, Apple and other computer hardware manufactures began building webcams directly into laptop and desktop screens. This eliminates the need to use an external usb or firewire webcam
