Human communication was initiated with the origin of speech approximately 100,000 BCE. [1] Symbols were developed about 30,000 years ago. The imperfection of speech allowed easier dissemination of ideas and eventually resulted in the creation of new forms of communication, improving both the range at which people could communicate and the longevity of the information.

It was the first electrical telecommunications system and the most widely used of a number of early messaging systems called telegraphs, that were devised to send text messages more quickly than physically carrying them. [1] [2] Electrical telegraphy can be considered the first example of electrical engineering. [3]
In 1900, Reginald Fessenden was able to wirelessly transmit a human voice. Millimetre wave communication was first investigated by Bengali physicist Jagadish Chandra Bose during 1894–1896, when he reached an extremely high frequency of up to 60 GHz in his experiments. [25]
It was, in 1920, extended by 900' using two self-supporting steel lattice towers, 60' on a side. These were removed ca. early 1923, when a new extension, running to the ENE, towards Llanberis, was built using six new guyed lattice masts of 400'. One mast, number 13, collapsed during construction. It was rebuilt and reassigned as mast 17.
The institutionalization of communication studies in U.S. higher education and research has often been traced to Columbia University, the University of Chicago, and the University of Illinois Urbana-Champaign, where early pioneers such as Paul F. Lazarsfeld, Harold Lasswell, and Wilbur Schramm worked.
In the late 1800s and early 1900s, a new breed of women started to emerge from the depths of circus tents around the world: the strong-woman. These women quickly drew large crowds of circus lovers ...
Before the discovery of electromagnetic waves and the development of radio communication, there were many wireless telegraph systems proposed and tested. [4] In April 1872 William Henry Ward received U.S. patent 126,356 for a wireless telegraphy system where he theorized that convection currents in the atmosphere could carry signals like a telegraph wire.
