When was communication invented

Before television, people relied on radio and live entertainment to amuse themselves. From the late s, a few inventors had been experimenting with displaying images on a screen. It was a Scottish man named John Logie Baird who was successful in showing moving images on a screen in Several others continued to improve on his original design.

The cathode ray tube was used to create better output on screens. The first TV images were halftones, and then black and white, before color was finally introduced in Television continues to rule many living rooms across the world and we have far more to choose from in terms of sizes, models and even channels. Even before the Internet was fully evolved, electronic mail had been developed in the s as a way to send messages from one computer to another.

In the early days, both users had to be online at the same time in order to send and receive messages through a central system. In , the first email was sent by Ray Tomlinson, an American programmer. Instead of only being able to send text messages, we can also transfer multimedia and other attachments as well. Through the s, email quickly caught on as the quick, new way to communicate. While email is still one of the main means of modern communication methods, it is facing some competition from instant messaging and social media services.

In the s, a researcher at Motorola named Martin Cooper began working on portable communication devices. In , he developed a type of mobile phone. For the next couple of decades, the main aim of many cell phone manufacturers was to make phones that were smaller and sleeker.

With digital cell phones, new options were added, such as the ability to store phone numbers, change ring tones and even play games. In recent years, this has given way to smart phones.

These devices combine computing power into a cell phone, giving the user Internet access and basic computer functionality all in a pocket-sized cell phone. Advancement in communication at first progressed quite slowly.

Different signs and symbols were used to deliver messages. Rock Carvings Petroglyphs were introduced in 10, B. These rock paintings drew pictures to convey stories. The carvings on the rock surface were also known as Rock Art. Later on, graphic symbols were used to present ideas or concepts. Chinese created characters for communication as well. Alphabets were created at the last. Evolution of communication was easier after the alphabet. These signals were used to send messages.

They were mostly used in China. 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. Altogether, this allowed for a practical system for printing books in a way that was efficient and economical. By the 19th century, the world was ready to move beyond the printed word.

The early process he pioneered, called heliography, used a combination of various substances and their reactions to sunlight to copy the image from an engraving. Other notable later contributions to the advancement of photography include a technique for producing color photographs called the three-color method, initially put forth by Scottish physicist James Clerk Maxwell in and the Kodak roll film camera, invented by American George Eastman in The foundation for the invention of electric telegraphy was laid by inventors Joseph Henry and Edward Davey.

In , both had independently and successfully demonstrated electromagnetic relay, where a weak electrical signal can be amplified and transmitted across long distances. A few years later, shortly after the invention of the Cooke and Wheatstone telegraph, the first commercial electric telegraph system, an American inventor named Samuel Morse developed a version that sent signals several miles from Washington, D. And soon after, with the help of his assistant Alfred Vail, he devised the Morse code, a system of signal-induced indentations that correlated to numbers, special characters, and letters of the alphabet.

Naturally, the next hurdle was to figure out a way to transmit sound to far off distances. And while he and others explored the notion of transmitting sound across distances, it was Alexander Graham Bell who ultimately was granted a patent in for "Improvements in Telegraphy," which laid out the underlying technology for electromagnetic telephones.

But what if someone tried to call and you weren't available? Sure enough, right at the turn of the 20th century, a Danish inventor named Valdemar Poulsen set the tone for the answering machine with the invention of the telegraphone, the first device capable of recording and playing back the magnetic fields produced by sound. The magnetic recordings also became the foundation for mass data storage formats such as audio disc and tape.

Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. A Scot, Alexander Graham Bell invented the telephone in The first telephone exchange in Britain opened in The first telephone directory in London was published in The first telephone line from Paris to Brussels was established in The first line from London to Paris opened in The first transatlantic telephone line opened in 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.
