The phone was invented in 1932 by the American scientist Alexander Bell.

Initially, the devices were large, expensive and slow, "a toy of the rich." Today, the phone is almost everyone, and it can fit in your pocket.

How did these communication devices change?



Evolution of phones was caused by the struggle of companiesAnd technological approaches, views on business. The initiative moved (together with financial success) to the firm that was in the trend, better than others solved the problem of communication of ordinary users.


The American company AT & T became the first telephoneCompany in the world. She bought a patent from Bell and became a kind of monopoly. She managed to connect the largest cities of the USA to the wireline channel: New York, Los Angeles, Philadelphia and Boston.

Telephones all decreased and decreased in size. But the real revolution was the phone-fax offered by the company-manufacturer of Xerox printers. Thousands of entrepreneurs were able to exchange documents in no time - this was a breakthrough in the history of the telephone industry.


And yet the main drawback of the phones was theirAttachment to the wires. Science enabled the use of electromagnetic waves as a means of transmitting information. AT & T returned to the market of major communication players, showing the world a cellular connection, named so because of the honeycomb principle (information is transmitted over the radio waves from one hexagonal site to another, in the center of each cell is a tower-radio antenna). Mobile phones weighed then ten kilograms and were used exclusively in cars.


Siemens and Nokia in the early 90-ies of the XX centurySolved the problem of dimensions. Cell phones could now be put in a pocket. And English students used the protocol error to exchange information for free. So there were SMS-messages.
