Zoom? Try having a video conference call 10 years ago. I remember going to an HP corporate office (in Taiwan, if I remember correctly) in 2012 where they proudly demonstrated a video conference room that worked well. Setting up calls using WebEx back then was slow, had poor performance, and usually somebody failed to join and had to call in.
The main thing that happened here was bandwidth. Back then you'd be lucky if someone had the 2mbps needed for a reasonable HD call. The underlying technology has not really changed since then though.
And the commidiziation - ten years ago was 2014 and things like GoToMeeting existed, and were "barely capable" but could share screen, audio, and if your connection was good enough, video from your grainy webcam.
But lots of people weren't using that, they were still stuck with telephony-based videoconferencing, with polycom devices in the middle of a conference table and dual ISDN lines and stuff, stuff built out in the prior decade.
And then connections and cameras got good enough that Zoom could "just work" without all the hassle of following the rules, etc.
In about 2005, while I was IT for a startup, I worked with a counterpart at an investor (Deloitte maybe?) whose job was largely coordinating video calls in advance of meetings. We’d exchange IP addresses and SIP addresses and whatnot so that our Polycom could talk to their Cisco or whatever it all was. She and I would join 30 minutes beforehand to make sure it all worked, stand by during the meeting in case there was trouble, then come back after the execs were finished and shut it all down. The calls were at least as good as Zoom or Teams today, at the expense of two IT people and dedicated equipment. The execs never knew it not to work great. A much simpler time. We have come a long way.
