The creation of the Television

The creation of the Television was something really slow, because the means were difficult due the ancient technology. Only by 1923 Vladimir Zworykin, a Russian man who lived in the USA, created the iconoscópico tube (which is the basis of the television). But only in 1928 was held the first TV broadcast made ​​by Ernst F. W. Alexanderson, who worked for GE. This television was still very rudimentary, being more like the radio that showed blurred images.  
Only in 1935 television really came in, but was only can watched in 22 public rooms in Germany.
After the 2nd World War the TV became popular, thanks to falling prices and rising incomes in general
In 1954 was created the color TV, a few years later, in 1962, the first satellite transmissions from one continent to the other, made the TV the primary means of communication in the world ..
