A hologram is a special kind of graphic that is produced by a light and that looks three-dimensional. In other words, a 3D image that exists in real space. Just like in Star Wars.
Are AR, VR also holograms?
No. AR, VR are different technologies that allow users an immersive experience. With VR, you are experiencing reality in the virtual world, and AR gives you the ability to augment the reality. Both technologies require some device or headset to see virtual graphics. On the other hand, hologram technology doesn’t need a headset.
What about HoloLens?
Hololens is a headset that allows you to augment reality, and it also allows you to interact with it. That’s why it is called Mixed Reality (MR), but it is not a hologram technology, even though Microsoft repeatedly called the images “holograms” during demos.
But, I saw a video that shows flying animals, whales, and other cool things, but I don’t see people wearing any headset to see them.
That’s because those videos are mostly fake. AR, VR, MR, XR, and Hologram are the most exciting words nowadays, so companies use these words in a context to attract people without worrying about they are real or not. These technologies are still unreal for most people anyways.
What is a hologram then?

The Pepper’s Ghost Effect
The Holographic Smokescreen
Based on LEDs which are programmed to create images that present a 3D holographic effect.
Holographic Spinning Mirror Technique
Spinning mirror systems are used to build interactive 3D graphics and autostereoscopic visuals visible to multiple simultaneous viewers, since a different view can be perceived by each viewer depending on the angle of vision Wikipedia
