While rival news networks are trying hard to make us believe that CNN holograms were actually tomograms, CNN news anchors continue to refer to their election-night 3D stunt as a hologram.
Here’s how the CNN hologram image was done and beamed live from Chicago to New York.
1. This is a temporary CNN tent erected in Chicago where the "hologram" news reporters were stationed and talking live to their counterparts in New York.

2. This is the inside look of the CNN hologram tent. This is a round green-screen room with 35 high-def video cameras surrounding the news reporter who’s standing in the middle.

3. The cameras in the green room "talk" to the New York studio’s cameras, meaning that when a New York camera moves, it "tells" the cameras in the tent which direction it’s moving and keeps the subject in the correct proportions.
4. And there you have it. The inset image shows the real view in Chicago though we saw something totally different on our TV screens.
In case you noticed some blue glowing edges around the hologram image, they were added intentionally to avoid confusion.

OK, we get it you are a bit too impressed with this technology. Now, can you stop promoting it. It’s nowhere that exciting. Its very expensive and pointless technology when you can just have the subject straight live like normal news channels. However, had it been a hologram, I would have understood your excitement.

I was watching CNN the night of the election, and I could not come up with a decent explanation as to why CNN would waste money on a hologram segment that wasn’t really that impressive.

The other networks are right. It’s not a hologram. See how they’re green-screened? And see how he’s not showing up in the big blank space that the other guy’s talking to? That’s because it’s not a hologram. In a hologram, he would be visible to the guy talking to him. His image would be visible in *real life* without the computers needing to insert him into the TV footage.

“The sound was really complicated”.
Uh, how was the sound any different than if it was just a normal video remote interview? CNN is being really disingenuous about this whole thing.
