The segments of "Zoom" were filmed out of order, so for continuity purposes, every cast member always wore the same outfit and had their hair styled the exact same way for each episode.
The ZOOMers went by their first names on the show, and some of them went by nicknames: "Buzz"'s real name is Kevin, and "Shing-Ying"'s real name is Elena.
The show's content was 100% comprised of viewer letters and e-mails sent in by real kids.
Every season always had seven cast members: four girls and three boys.
First-season cast member Jared Nathan tragically died in a car accident on December 28, 2006, when the car in which he was a passenger smashed into a tree.
