The means of communication developed along with the formation of civilization. In the 19th century, the telegraph came to the rescue of traditional letters sent in postal envelopes. But he was not very easy to use. The real revolution in technical means of communication took place after the invention and widespread introduction of the telephone.

Step 1
The history of the appearance of the phone is very interesting. Several people approached the invention of this method of transmitting voice over a distance almost simultaneously, and yet Alexander Bell is considered to be the creator of the first telephone. A new type of communication was patented in 1876, but the first usable device was created a little later. A new era in communication technologies has begun, affecting all spheres of life, without exception.
Step 2
The physical effects underlying telephony were discovered, as usual, by accident. Bell has worked with people with speech and hearing impairments for a long time. By the nature of his work, he had to study acoustics. Once, while working on a device for amplifying sound, he discovered the possibility of transmitting voice over a distance over wires.
Step 3
This discovery turned the whole world upside down. Figuratively speaking, since the invention of the telephone, the distance between different parts of the planet has been greatly reduced. The telephone for talking over the wire was shown to the general public. The invention impressed the business world so much that Bell was soon able to found his own telephone company, which quickly grew into a powerful and prosperous concern. This is how a new industry emerged.
Step 4
The telephone did not immediately gain the confidence of the general population. At first, there were even those who demanded to start criminal prosecution against the inventor, considering him a swindler hoping to get money from gullible inhabitants. However, passions gradually subsided. Everyone could be convinced that the technical novelty not only works properly, but is also capable of radically changing the life of people, making life more dynamic and comfortable.
Step 5
The widespread adoption of telephony has solved many of the problems that previously had to be tolerated. Now it was possible in a matter of seconds to establish a voice connection with a subscriber who was sometimes on the other side of the planet. The telephone has changed the way we do business by giving it a dynamic. The transfer of important business information began to take minutes, not hours and days, as it used to be.
Step 6
For more than a century, telephone communications have been developing, becoming high-quality and affordable. Another technological breakthrough came when scientists discovered the principles that made the telephone cordless. The massive introduction of mobile and satellite telephony began at the end of the last century. Now, for a conversation with a subscriber, it was not required to lay expensive telephone lines that needed maintenance.
Step 7
The modern mobile phone has become an integral part of everyday life in all corners of the planet. With it, you can not only talk with loved ones or send them a short text message. The telephone has turned into a powerful multifunctional complex that allows you to manage your bank account, access the Internet, and listen to the radio. Today it is almost impossible to imagine life without this little mobile assistant.
