The first video conference technology dates back to the audio wires of the 1870s and Bell Lab’s video phone in 1927, which has adapted and evolved into the modern video conference of today. From the early Bell Labs patents to the introduction of the word “video” to the English language and all the way up to the first-ever Lifesize 4K video conference call, the history of video conferencing is a fascinating example of technical progress.

Let’s go back in time to the very beginning when video conferencing was first introduced as a faster, more efficient way to communicate, how it evolved throughout the years, and how a company like Lifesize has continually innovated and redefined the future of workplace communication.
