The early 1990s. Students at Cambridge University in the Computer Science Department invested in the first web camera in 1991. This primitive but highly innovative device could only provide 129×129 pixel grayscale pictures at one frame per second. This invention, which is now standard on most new computers, paved the way for online video conferencing. In the early 1990s, a student at Cornell University wrote a program called CU-SeeMe. This became the first video conferencing platform and was released on macOS in 1992. Two years later, in 1994, the software program became available on Windows.
