At this year's Coachella music festival a "hologram" of Tupac Shakur stole the show. Video of the realistic looking performance spread across the internet almost immediately, setting off enthusiasm for holograms in a way that we've never seen before.
The reaction to the "hologram" of Tupac was so extreme, beyond anything we've seen even with 3D, that we decided to take a closer look at the technology.
Holography, as it's referred to by those who study it, is a true science and has been studied at academic institutions like MIT for years, and the innovation taking place is startling.
The technology already exists to create hologram TV's and researchers and working to develop processors fast enough and cheap enough to make them a viable consumer option.
In Japan's bid to host the 2022 summer Olympics they included the ability to broadcast live holograms of soccer matches to stadiums all over the world, allowing you to watch a match from a stadium in America while it's played live in Tokyo.
What's funny is that it turns out Tupac's performance wasn't actually a hologram. It was a 150 year technology called Pepper's Ghost, which is a projection technique, not a hologram.
But Michael Klug (KLOOG), a veteran of MIT and Co-Founder of hologram producer Zebra Imaging, isn't complaining. He spoke with us this week and seems resigned to the fact that the term hologram has been co-opted by similar technologies, but he's just happy that people are talking about holograms.
