CRT televisions, or Cathode Ray Tube televisions, were a type of television that used a cathode ray tube to display images. They were the dominant technology for televisions from the 1950s to the early 2000s. The CRT television consists of a vacuum tube with an electron gun at one end and a phosphorescent screen at the other. The electron gun fires electrons at the screen, which then emit light when struck by the electrons. The image is created by scanning the screen with a beam of electrons, which are directed by magnetic coils.

CRT televisions were known for their high-quality images, with sharp contrast and vibrant colors. They were also relatively inexpensive to produce, which helped to make them widely available. However, they had several drawbacks. They were large and heavy, and required a significant amount of power to operate. They also emitted a significant amount of heat, which could cause them to overheat and fail. Additionally, the phosphorescent screen could burn out over time, requiring replacement.

The advent of LCD and plasma televisions in the late 1990s and early 2000s began to phase out CRT televisions. These new technologies offered thinner, lighter, and more energy-efficient alternatives. Despite their eventual decline, CRT televisions remain a significant part of television history, representing a pivotal era in the development of television technology.
