The television is an invention that over 98.5% of American families have in their house today.

The TV is mostly used for entertainment. It also shows news that informs people what is happening locally and around the world.

The TV is also one of the biggest advertisers using commercials in between shows.

In 1862 Abbe Giovanna Caselli invents his Pantelegraph and becomes the first person to transmit a still image over wires.

Then in 1906 Lee de Forest built a vacuum tube that worked in the first mechanical working television.

In 1940 Peter Goldmark invents the first color television with 343 lines of revolution.

In 1948 cable television was introduced in Pennsylvania.

In 1981 NHK demonstrates the HDTV which had 1,125 lines of revolution.

In 1992 the first 21-inch full color plasma TV was introduced

In 2010 the first 3-D televisions were put on the market.

From when the first television was made by Lee de Forest, there has been many changes and improvements to it.

After the TV was first invented, in 1936, coaxial

cable was invented to transmit television signals.

The first TV started out with black and white pictures until 1940 when the first color TV was built.

Later on in 1948 cable became available to people that owned televisions. This provided them with more channels to view.

Then finally in 1956 the first remote control was made for the TV that was made with wires. The only problem was that the wires would not work in sunlight.

Later the first HDTV was made for viewers to get a better and higher quality image.

And in 2010 the first 3D TVs were sold letting viewers watch their programs in 3D.

Contains a lot of lead Many LCD TVs use lamps that contain

mercury so they are harder to dispose of.

People don’t know how to dispose of televisions properly. Now there is a big concern about electronic waste.

The newer TVs are requiring more electrical power to run.

More people are becoming less active and obese because of TVs. Instead of exercising more people are staying home and watching television.

TV can influence the way people think, and manipulate their decisions.

Children are becoming more obese and lazy. In 1963, 4.5% of children ages 6 to 11 were seriously overweight; by 2009, this percentage had more than tripled.

TV influences a lot of violence to viewers in shows and movies. 80% of Hollywood executives think there is a link between TV violence and real-life violence.
