I feel like anywhere you see a flat 2D image could be a 3D hologram eventually. And holograms give the "whole message", so more information, better information, clearer information. That's the potential. So portraits, some day hologram cameras, CAD output, advertising, and yes eventually hologram television/displays.

But we are starting with something more simple, and not trying to promise everything to everyone. That does mean looking for initial use cases that will take off early.
