The oldest type of monitor is the cathode ray tube (CRT) monitor. Developed in the late 19th century and popularized in the mid-20th century, CRT monitors use electron beams to illuminate phosphorescent screens. They were the standard for televisions and computer displays until the rise of flat-panel technologies like LCD and LED. CRTs are now largely obsolete, replaced by more energy-efficient and space-saving display technologies.
