Closed-captioning helps hearing-impaired people read what is being said during a television program.

Digital TVs also have space for many more channels. Analog TVs in the United States had a limited number of channels. Digital TVs have hundreds of channels.

HIGH-DEFINITION TVS

Companies now make high-definition televisions (HDTVs) to receive digital signals. HDTVs have wide and flat screens. Wider screens give people the feeling that they are watching a movie screen.

HDTVs have wide screens. Many are thin enough to hang on a wall.

Wide screens can also be larger. In 2014, Samsung launched the largest home TV with a 110-inch (279-centimeter) screen. It cost $150,000! Most people can’t afford a screen that large, but many have 40- or 50-inch (102- or 127-centimeter) or even larger flat screens in their homes.
