monochrome television

Monochrome television, also known as black-and-white TV, displays images using shades of gray, ranging from black to white. It transmits visual information through electrical signals that control the brightness of the picture on the screen. Unlike color TVs, it doesn't provide color details, so images lack hue. Developed in the early days of television technology, monochrome sets were widely used until color broadcasting became standard. Despite its simplicity, monochrome television was an important step in the evolution of broadcast technology, offering viewers visual entertainment and information before the advent of more advanced color systems.
