Reading: TELEVISIONS

Televisions turn the data they get from cables and signals into sounds and images.

The first TV, which had only one colour dates back to 1925 and the first TV station was built three years later in New York.

The world’s first electronic television was invented by a 21-year-old man named Philo Taylor Farnsworth.

When the TVs were first displayed at the 1939 World’s Fair, they were only five inches big.

In the United States, the first states to have commercially licensed television broadcasting networks were New York and Pennsylvania. These networks were created in 1941. Colour televisions went on sale in 1953, and today people have the chance to watch TV in 3D.

The first American advertisement aired on NBC was for a Bulova watch and lasted for 10 seconds.

In the 1980s, home video cassette recorders became widely available. Viewers gained the chance to record and replay programmes. 

At the start of 1993, 98% of American households owned at least one TV. Today, televisions can be found in billions of homes around the world.

2005 was the year when flat screen TVs and HDTVs were introduced for the first time.
