the Outer Limits episode "The Mice"

[Preston]

This is one of my favorite Outer Limits episodes, so I was wondering if MICE was the very first Television episode to use a teleportational transporter. I know that the teleportational device from THE FLY came before The Outer Limits but THE FLY was a theatrical movie. So what I wonder is if MICE was the first to use it for Television??

could be, although i seem to remember a Twilight Zone episode that had a similar contraption in it as well.
