Like so many technologies, the concept of video communication and video conferencing was way ahead of the technology of its day. Soon after the telephone was invented in the late 1800s people were dissatisfied with just hearing the other party -- they also wanted to see the other party.
It was a long trip from the first video call to Zoom meetings with a dozen people -- and many steps toward video calls since they provided the only means of telecommunication for decades. Let’s go back to the beginning of video camera’s emergency and see how it evolved.
The concepts of video conferencing appeared from Bell Labs
The first stable and operational TV cameras entered the market, setting the stage for video communication.

PictureTel was invented and take into commercial use
Some MIT students and their professor formed PictureTel Corp. in 1984. It invented the first commercial video codec for more efficient data transfers. In 1989, AT&T chose PictureTel for an international video conference. It provided two-way, real-time audio and full-motion video connections between PictureTel headquarters and the AT&T office in Paris. In 1991, PictureTel became an IBM multimedia business partner and pursued a PC-based video conferencing system.
Internet boom and digital telephony advancements. The first webcam in 1991 was formed. It provided a 129×129 pixel grayscale picture at one frame per second, pulling images three times per minute.
