Year: 1977

Princess Leia is the OG when it comes to holograms. In 1977, when special effects were still in their painfully awful and awkward embryonic stages, George Lucas and his team came along to completely change the game. While lightsabers, intergalactic warfare, and the Death Star were all impressive technical achievements in their own right, the special effect that first caught everyone's eye was Princess Leia's holographic plea for help. Since then, all other holograms have simply been imitators.
