A webcam is a small digital camera attached to any computer that is connected to the Internet. It is mainly used to take pictures and make short films of the surrounding area (mostly of its owner). Other uses might include chatting, security, and video conferences over the Internet.
The first webcam was pointed at the 'Trojan room coffee pot' at the computer science department of Cambridge University. The camera has been installed in 1991 and was connected to the internet in 1993. At August 22, 2001 it was finally switched off.
