3D is a TV feature that makes images look like they are popping out of the screen, giving a sense of depth. It works by showing two slightly different images to your left and right eye, often using special 3D glasses.
In Kenya, 3D TVs were popular around 2010–2015, but they faded out because streaming services and broadcasters rarely offer 3D content.
Compared to normal 2D, 3D tries to make movies and sports feel more immersive, but many people found the glasses uncomfortable.
