Apparently related to Scots soom (“to buzz, hum”), dialectal English and Scots soom, swoom, sweem (“to spin or twirl at high speed”). Compare also dialectal English sweem (“to swoon, become dizzy or faint”).

Zoom · verb, noun3
From Zoom, a videoconferencing software by Zoom Video Communications; renamed as such (from Saasbee) in May 2012 by Jim Scheinman after the American children's book Zoom City (1998) by Thacher Hurd for ostensibly encapsulating creativity, happiness and exploration. Scheinman had "been saving the name Zoom for a long time."
