For example

Yeison: communication evolved with humans. Then came the enemy of the communication THE DISTANCE, which prompted the emergence of new forms of communication

Mallely:  If so, around 1879 the phone in the beginning was quite rudimentary, to achieve the user to communicate with someone totally dependent on the operators at the plants, but it was in 1889 when Almon B Strowger patented a system of automatic telephone exchange equipment and the which did not require the presence of operators to get two people to communicate.
