They are primarily used in video telephony, live streaming and social media, and security. Webcams can be built-in computer hardware, like a laptop, or peripheral devices, and are commonly connected to a device using USB or wireless protocol.
Webcams have been used on the Internet as early as 1993, and the first widespread commercial one became available in 1994. Early webcam usage on the Internet was primarily limited to stationary shots streamed to web sites. In the late 1990s and early 2000s, instant messaging clients added support for webcams, increasing their popularity in video conferencing. Computer manufacturers later started integrating webcams into laptop hardware. In 2020, the COVID-19 pandemic caused a shortage of webcams due to the increased number of people working from home and children attending school remotely.
