4. Video Calling - A Space Odyssey, 1968

These days more than ever, video calls have become an essential part of the way we communicate with our families and friends, and at work. But while video calls are almost as common as regular calls nowadays, back in the 1960s this was not yet a possibility. Although the concept of video calls was still under development throughout that decade, the importance of video calls was highlighted several times during the 1968 movie A Space Odyssey. The tech was released that same year.
