3-D television .The first film in 3D was shown in the cinema in 1922. No, this is not
a typo. It was really in 1922. And in the year 1928 the first 3D television was
made. It was made by the inventor of the normal television John Logie Baird.
But no one was interested in the 3D technology for a long time because it was
extremely expensive. In the 1950s several 3D films were made but they were
considered as something unusual. The real breakthrough came with the invention
of the format IMAX 3D which was introduced in 1986. Nowadays all the TV
producers make 3D televisions. However, for some people 3D doesn't exist
because their eyes are bad and they cannot see it.
GPS. GPS stands
for global positioning system which is a positioning system run by the Army of
the United States. It is possible to find the exact position and time wherever
on the Earth. Originally this system was planned to be used only for the Army.
The system was started in 1994 when all 24 satellites were placed on the orbit.
Normal people started using GPS in 2000. Nowadays GPS has 32 satellites which
are 20 km above the Earth.

which were big and heavy. Nowadays the smart phones are thin, and light and
they can do a lot of things. Besides telephoning you can listen to music,
connect to the internet, and you can play games there too. The first smart home
was introduced by IBM at the beginning of 1990s. This phone had a calendar,
address book, clock, calculator, notebook, email and a few games. It had a
touch display, but it was only black and white. But at the beginning everyone
thought that phones like this where unnecessarily expensive and useless. It was
only 10 years later when Steve Jobs introduced iPhone and smart phones became
incredibly popular.
