Breaf history of communication

The history of communication dates back to prehistory, with significant changes in communication technologies (media and appropriate inscription tools) evolving in tandem with shifts in political and economic systems, and by extension, systems of power. Communication can range from very subtle processes of exchange, to full conversations and mass communication. Human communication was revolutionized with speech approximately 100,000 years ago. Symbols were developed about 30,000 years ago, and writing in the past few centuries. 

The history of telecommunication - the transmission of signals over a distance for the purpose of communication - began thousands of years ago with the use of smoke signals and drums in Africa, America and parts of Asia. In the 1790s the first fixed semaphore systems emerged in Europe however it was not until the 1830s that electrical telecommunication systems started to appear.

Afer discovering electrical telecomunication systems it all devoloped relatively fast keeping in mind that it took us couple of thousand years to develop alfabet.

Chronology is as follows;  

• 1893: Wireless telegraphy
• 1896: Radio
• 1914: First transcontinental telephone calling
• 1927: Television
• 1927: First commercial radio-telephone service, U.K.–U.S.
• 1930: First experimental videophones
• 1934: First commercial radio-telephone service, U.S.–Japan
• 1936: World's first public videophone network
• 1946: Limited capacity Mobile Telephone Service for automobiles
• 1956: Transatlantic telephone cable
• 1962: Commercial telecommunications satellite
• 1964: Fiber optical telecommunications
• 1969: Computer networking
• 1973: First modern-era mobile (cellular) phone
• 1981: First mobile (cellular) phone network
• 1983: Internet
• 2003: VoIP Internet Telephony

In the future we can expect further development of the VoIP telephony as the 4 and 5G technology. Wireless communication and video calls will be the main point of developers focus and to point almost all of the communication over the internet through VoIP and IT systems.
