Communication Growth in 20th Century. Communication begins for all of us when we are too young to speak but convey our messages by facial expressions. This method is known as pre-verbal communication.
Language it the vehicle which allows people to communicated their thoughts and ideas to other people and through print to save those ideas and not only share them with their contemporaries but to pass them down to the generations to come.
The development of the electric telegraph in the 1840s and the telephone in the late 1870s made rapid long-distance communications possible. Both media began in local areas and then rapidly spread to connect large parts of the Nation and the world.
The 20th century brought the invention of “radio” a form of wireless telegraphy which increased the mobility of communications and was used in point to point and multi-point communications. Later with the invention of the amplifying vacuum tube the radio transatlantic communications became possible.
On the domestic front, the Radio Act of 1912 established a radio licensing regime within the Department of Commerce and required certain ships to carry radios for communications. Due to conflict between amateur radio operators and the U.S. Navy and corporations, the Radio Act further regulated private radio communications, thus setting the precedent for federal regulation of wireless communications. This act was just the first step in the many regulations that would be enacted to control the private use of communications.
The development of electronic surveillance for legitimate purposes such as intelligence and law enforcement investigation, as well as for illegitimate purposes, spurred enactment of a number of laws intended to comprehensively address such activities. Congress enacted the first federal wiretap statute as a temporary measure to prevent disclosure of domestic telephone or telegraph communications during the First World War.
The first experimental communications satellite was launched in 1962. It was the first satellite to receive, amplify, and simultaneously re-transmit signals from earth. The development of satellite communications available not only to governments but also the commercial sector and individuals led to even greater volumes of communications worldwide.
The Internet is a globally distributed network comprising many voluntarily interconnected autonomous networks. It operates without a central governing body. However, to maintain interoperability, all technical and policy aspects of the underlying core infrastructure and the principal name spaces are administered by the Internet Corporation for Assigned Names and Numbers (ICANN), headquartered in Marina del Rey, California. ICANN is the authority that coordinates the assignment of unique identifiers for use on the Internet, including domain names, Internet Protocol (IP) addresses, application port numbers in the transport protocols, and many other parameters
