CRT televisions, or Cathode Ray Tube televisions, were the standard type of television for many decades. They work by using an electron gun to shoot beams of electrons onto a phosphorescent screen, creating images. These televisions are typically bulky and heavy due to the large glass tube that houses the components. Although CRT televisions have largely been replaced by newer technologies like LCD and LED screens, they were known for their deep blacks and vibrant colors. Many people still appreciate them for their nostalgic value and the unique viewing experience they provide, especially for older video games and movies.
