What is a Video Call?

A video conference is a communication method that allows individuals or groups to interact and communicate in real time using audio and visual technology.

Via the use of technology, persons situated in different geographical places may engage in real-time communication by means of voice and video through video conferencing. It replicates in-person interaction by generating a virtual meeting space where individuals or teams may see and audibly perceive each other. Real-time audio and video streams are sent, facilitating remote communication via the use of video cameras, microphones, and internet connectivity.

The background of video conferencing

Video phones were initially experimented with by AT&T Bell Labs and John Logie Baird in the 1920s, which is when the first developments in video conferencing happened.

Germany also conducted early attempts with video conferencing in the 1930s. Among the earliest devices employing this technology were picture phones, which conveyed still images over phone lines.

Nevertheless, it was confined to Mac; hence, in 1995, a Windows version was made available. QuickCam was ranked as one of the top computer devices ever invented by Time magazine in 2010.

The CU-SeeMe video conferencing tool for Mac was established in 1992 by Cornell University's IT department team. In 1994, they started development on the Windows software. The first internet radio stations were formed in 1995 with the commercial release of the CU-SeeMe software.

In 2004, a number of firms started employing video conferencing systems for the first time as internet technology became more generally accessible and more cheaply priced. The usage of video conferencing rose during the 2010s.
