When was communication started

Chinese guards released smoke into the air. Smoke is depicted as a message to The Great Wall of China. A famous Greek Historian Polybius used smoke signals to represent the alphabet. Pigeons are known well for their directions. They were known to find their home, even after traveling long distances. People used to attach small letters to their necks, hoping they would fly to the receiver. Pigeons were also used by Ancient Romans to tell owners how their entries had been placed.

They carried essential messages and helped in evolution of communication. With raising awareness, people started to use courier services. Letters were delivered from one person to another through postal services. These systems were organized in India, China, Persia, and Rome. A Frenchman De Valyer started a postal system in The use of mailboxes and delivery of letters was done through the system. Newspapers are still a wide form of communication used. Every other house has a newspaper delivery every day.

These papers deliver written news and also other important national events taking place. Two types of Newspapers are National and International. Their types depend upon the news they deliver about. The first printing press system was introduced in by German Johannes Gutenberg. The newspaper started to get more attention and changed communication forever. With the advent of Print Media, Radios were introduced after that. Radios are a source of news as well as entertainment for people. Wireless signals were studied and tested in detail.

The scientists practiced using wireless power to share content. Radios are still installed in mobile phones, car systems. They were once a very important medium of communication.

The first electrical communication system to send text messages was called Telegraph. Sending letters required energy and patience to wait for a reply. Telegraphs were introduced to send text messages more quickly than written messages.

It helped in sending information across the country. The first telephone was introduced by Alexander Graham Bell in Within 50 years of its invention, telephones became an essential part of every household and office. The devices transmitted human audio into signals. These signals were then transmitted through wires. Landline telephone service began in s. People could talk on calls for hours through long distances. It was the most reliable form of the communication system. Mobile phones were introduced in and the mode of communication was changed entirely.

Even today, Televisions are a great source of entertainment. They are a mode of indirect communication to the larger audience. Many people in history put in tremendous efforts to introduce Televisions.

But with the advancement, colors were added to the screen. Today, there are several features in Televisions that provide us more entertainment and information. The world of the Web has brought people closer. Satellites support the internet.

Through the internet, we can search for anything, anywhere in the whole world. Wireless connections via Wi-Fi began in Since then, people seem to be addicted to the internet. Nowadays, every small activity of our lives, business, and education involves the use of the internet. We highly depend upon the internet for our development as a nation as well as a generation. Microsoft Business Email is the most formal way of communication used in offices.

John Vittal in developed a software to support mails. In modern times 'town criers' hold an annual contest to discover which of them can shout a comprehensible message over the greatest distance. The world record is less than metres.

Already, at that short range, a more practical alternative is to run with the message. The history of communication is mankind's search for ways to improve upon shouting. When running with a message, to convey it in spoken form, it is safer to do it oneself. Sending anyone else is unreliable, as the game of Chinese whispers demonstrates. So another requirement for efficient communication is a system of writing. Messages carved on stone pillars communicate very well across time, down through the centuries, but they are an inefficient method of communicating across space.

The message reads only within reading range; its recipients must travel to receive it. The system is altogether more efficient if it is the message which travels. This requires yet another ingredient in the communication package - a portable writing material such as papyrus.

There are forms of long-distance communication not based on words. The smoke signals used by American Indians above all perhaps in westerns are of this kind. So are bonfires lit in succession on a line of hilltops. But such devices are only capable of conveying very limited pre-arranged signals, such as 'danger' or 'victory'. Some non-verbal systems are more sophisticated. The whistled language of Gomera, in the Canary islands, is used to communicate across deep valleys. It is well adapated to the islanders' immediate needs, but would be incapable of sending this paragraph as an accurate message.

For communication of this kind writing remains indispensable. In a telephone link from Britain to Australia was established. In Louis Braille invented an embossed typeface for the blind and in Isaac Pitman invented shorthand.

The first successful rotary printing press was invented by Richard M Hoe in Communication continued to improve in the 20th century. In Marconi sent a radio message across the Atlantic. Radio broadcasting began in Britain in when the BBC was formed. By half the households in Britain had a radio. Following the Sound Broadcasting Act, independent radio stations were formed. TV first became common in the s. A lot of people bought a TV set to watch the coronation of Elizabeth II and a survey at the end of that year showed that about one-quarter of households had one.

By about two-thirds of homes had a TV. BBC2 began in and Channel 4 began in Channel 5 began in Satellite television began in Britain in TV began in Australia in and in New Zealand in Meanwhile, in the first communications satellite, Echo was launched.

The laser printer was invented by Gary Starkweather in Martin Cooper invented the first handheld first cell phone in The first mobile phone call in Britain was made in The first commercial text was sent in In Britain, smartphones were introduced in In the early 21st century the internet became an important form of communication.
