Simple sells. Could have taken another century if group video calls hadn't recently been made simple. What's simpler: group video call or group audio bridge? The UX for most audio bridges: 1. difficult to setup account, dial-in #s, etc. in the first place (for the organizer of the call) 2. participants need to type in a long PIN 3. participants don't always know who is on the bridge, who isn't and who is but unknowingly muted. It helped of course that people had non business reasons to have Zooms, Facetimes, Hangouts etc. prior to the pandemic (whereas most people didn't have non-business audio conferencing accounts). And timing is always important - near ubiquitous broadband and personal compute being prerequisites for the mass video conferencing boom.
