So apparently CNN is now projecting holograms. Any ideas on whether the hologram is being seen in studio like we see it at home? What are the chances that we will see this in our homes soon?

It's not really a hologram. No, they don't see it in-studio (except on a monitor), nor will we see it in homes.

Edit: Here's an article about it:
