2.  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.

3.  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.

4.  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.

5.  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.

6.  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.

7.  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.
