Video conferencing has been around for a long time. The equipment is usually kept in a special room, always booked by executives due to the high value they derive in using it to enhance their collaborations.

Digital communications can take place using your laptop, your tablet, your smartphone, and even your watch, as the software is free, and the quality of the video is at an all-time high. Tech companies, such as Facebook, are now beginning to roll out more devices, such as the Portal, aimed at enhancing digital communications yet again.
