The Invention and Evolution of Television
Televisions show sounds and pictures. They get data from cables, discs, or over-
the-air signals and turn this data into sounds and images. People watch news and
shows on them. You probably call them TVs. John Baird made the first TV in
1925. It had one color and could only show 30 lines. This was just enough room
for a face. Though it didn't work well, it was a start. The first TV station was set
up in 1928 in New York. Very few people had TVs as the broadcasts were not
meant to be watched. They showed a Felix the Cat doll for two hours a day. The
doll spun around on a record player. They were experimenting with it and it took
many years to get it right.
By the end of the 1930s, TVs were working well. America got its first taste at the
1939 World's Fair. This was one of the biggest events ever. There were 200 small,
black and white TVs set up around the fair. The U.S. President gave a speech over
the TVs. The TVs were only five inches big but the people loved it. They wanted
TVs. But World War II was going on during this time. Factories were busy making
guns and bombs. When the war was over, TV spread across the country.
By 1948 there were 4 big TV networks in America. They aired their shows from 8
to 11 each night. Local shows were aired at other times. Most of the time, nothing
was shown at all. TV was not "always on" like it is now. Color TVs came out in
1953. They cost too much money for most. Also, shows were aired in black and
white. By 1965, color TVs were cheaper. TV stations started airing shows in color.
People had to switch if they wanted to see the shows.
Now most TVs are high-def. This means that they have many lines on them. This
makes the image clear. TVs have come a long way since Baird's 30 line set. High-
def TVs have 1080 lines. There are state of the art sets called 4K TVs. These TVs
have 3,840 lines. Some people watch TV in 3D. I wonder what they will come up
with next. Smell-o-vision anyone?
