CNN literally wowed their audience yesterday when they used the hologram technology to virtually transport 3D reporters from Chicago to their newsroom located in New York.
But now some some news reports say that what CNN referred to as "holograms" aren’t holograms at all but "tomograms."

CBS says that the images were tomograms, which are images that are captured from all sides, reconstructed by computers, then displayed on screen. Holograms, on the other hand, are projected into space.
National Post created an illustration (see above) to explain, what they say is, CNN’s trickery.
Well, we can’t really blame the CNN anchors here for saying "hologram" instead of "tologram" but what CNN did was something very unique and impressive nonetheless.
