Video conferencing is real-time video and audio meetings between people in different places, through platforms like Zoom, Microsoft Teams and Google Meet. It went from occasional to default during the pandemic and never went back.
In the office, video conferencing is now a room-design requirement: cameras, microphones and acoustics that make the room work for the people not in it. A meeting room that cannot host a video call well is, for most teams, not a meeting room. See meeting room AV.
