CRT television, which stands for Cathode Ray Tube television, was the dominant television technology for much of the 20th century. These televisions work by firing a beam of electrons from the back of the tube onto a phosphorescent screen at the front. The electron beam is guided by magnetic fields to scan across the screen line by line, illuminating the phosphors to create the image. The colors are produced by using three separate electron beams, one for red, one for green, and one for blue, which strike the corresponding colored phosphors on the screen.

CRT televisions are characterized by their bulky size and significant weight due to the vacuum tube and the necessary shielding. They offered a distinct image quality, often described as having good contrast and deep black levels, though their resolution was significantly lower than modern flat-screen televisions. The refresh rate of CRT displays also contributed to a perception of smoother motion for some viewers. While once ubiquitous in homes worldwide, CRT televisions have largely been replaced by newer technologies such as LCD, LED, and OLED displays due to their size, energy inefficiency, and lower resolution capabilities. Despite their decline in popularity, some enthusiasts still appreciate the unique aesthetic and viewing experience of CRT televisions, and they can still be found in some niche applications.
