My university has had an enterprise license for Zoom for several years, so we were all familiar with it. Prior to the pandemic we frequently used it for meetings across sites, so it was not a big jump to using it for all meetings.
Zoom has several features that make it useful in a corporate or academic setting. They have “Zoom rooms” which are setups where a TV, cameras, mics, and a controller are used so that several people in a room can connect to other people either in their own rooms or singly. Not a great feature today, but pre-pandemic was convenient for multi-site meetings.
They also have a local deployment option, in which the the backend servers are local to the client site, instead of in the Zoom cloud someplace. This can be important for places where security is important, as the local host controls all of the data.
Zoom also makes it easy for people to connect. Any device, including a POTS phone, can join a meeting. There is no cost to join a call, only to host one, though they have free options for hosting.
Enough with the sales pitch. I’m sure there is other software that can do similar, but Zoom was popular in the corporate space prior to the pandemic. Of course companies used their existing teleconference software during the pandemic, instead of getting something new.
The thing I find interesting is that the term used for these remote video calls changed pre- and post-pandemic. We used to have Skype meetings over Zoom. Now I occasionally have Zoom calls with Google Meet. Also, Zoom is better to say than, “Can I Microsoft Teams you and the client tomorrow?”
As for quality, I tested Zoom, Google Meet, and Facetime, and Zoom had the best video quality based on my own personal opinion, not any objective measure. That might be due to superior software, or Zoom simply using a higher bit rate video stream, so more bandwidth, than the others.
