The radio
The document provides a history of radio from its discovery by Heinrich Hertz in 1888 to its current and future states. It traces the key developments from Hertz's discovery of radio waves to Marconi's experiments with wireless telegraphy. By the 1920s, commercial radio broadcasts were transmitting information, music, and comedy to widespread audiences. The radio has since evolved with technologies like XM radio while maintaining its role as a mobile source of information and entertainment, currently listened to by 94% of Americans. Questions remain around radio's future as technologies like smart phones integrate its functions.
The Evolution of the Telephone
The telephone has evolved dramatically since Alexander Graham Bell patented the first electric telephone in 1876. Early phones required manual operation by switchboard operators to connect calls. As demand grew, automatic exchanges run by computers replaced human operators by the 1920s. Phones transitioned from wall-mounted landlines to portable cordless phones to today's smartphones that provide extensive computing capabilities beyond just voice calls. The iPhone transformed the industry with its touchscreen interface and integration of apps, internet, email and more.
The evolution of communication ppt (1)
The document traces the evolution of communication from early cave paintings and symbols through messenger runners, postal systems, telegraphs, newspapers, telephones, television, and the development of the internet and social media. Key developments include cave paintings from 30,000 BCE, the earliest forms of writing in Egypt and Mesopotamia, the Assyrian postal system in 600 BCE, Morse code in 1835, Alexander Graham Bell's telephone patent in 1876, John Logie Baird's first mechanical television demonstration in 1925, Tim Berners-Lee inventing the World Wide Web in 1989, and the rise of social networking in the 2000s.
History of the Telephone
Alexander Graham Bell invented the first telephone in the 1870s to allow for communication over long distances without writing letters. Early phones included the gallows phone and the dial phone. Modern phones are mobile devices like cell phones and smartphones that feature touchscreens and internet connectivity. Future phones may be waterproof and respond to grip without touching the screen, though developing such technology poses challenges. Telephones have become important for communication as they allow people to connect from anywhere rather than writing letters or traveling to distant locations.
The telephone fys project
Alexander Graham Bell invented the telephone in 1874 while working as a teacher for deaf children in Boston. He received a patent for the telephone in 1876. The first phone call was made on March 10, 1876 between Bell and his assistant Thomas Watson. The telephone rapidly evolved from the initial liquid transmitter to include new technologies like the dial phone, mobile phones, and smartphones. The invention of the telephone transformed society by allowing people to easily communicate over long distances and stay connected to distant friends and family.
Evolution of Communication
The document outlines the timeline of major developments in communication from the 6th century BCE to the modern day, including the development of the Phoenician alphabet, pigeon post, Morse code, the electric telegraph, telephone, radio, television, cellular networks, the internet, and social media platforms. Key developments include Alexander Graham Bell and Thomas Watson exhibiting the first telephone in 1876, the first radio broadcast in 1920, John Logie Baird transmitting the first television signal in 1925, and the creation of personal computers, the internet, Myspace, Youtube, and Twitter in later decades, which revolutionized how people interact and communicate globally.

Cell phones have evolved greatly since their origins in the mid-20th century. Early research into mobile phones in the 1940s used large vehicle-based phones, but the first handheld mobile phone call was made in 1973. The modern cell phone industry developed through 3 generations of technology, starting with analog networks in the 1980s, digital networks in the 1990s, and 3G technology in the 2000s which enabled streaming media and advanced cell phone features seen today. Cell phone technology has transformed communications and is predicted to continue advancing rapidly in the future.
Media timeline for ancillary tasks
Television was first successfully demonstrated in 1927 by Philo Farnsworth. The Internet originated in the 1950s as a government project and has since evolved to be used for communication and sharing data by scientists and researchers. In the late 1990s and early 2000s, pop-up ads were invented and became common on websites, often displaying advertising, before browsers enabled users to block unwanted pop-ups.

Cell phone Technology
Cell phones have evolved greatly since their origins in the mid-20th century. Early research into mobile phones in the 1940s used large vehicle-based phones, but the first handheld mobile phone call was made in 1973. Mass adoption of cellular technology was slow at first due to regulatory hurdles, but the introduction of digital networks in the 1980s and 1990s helped popularize cell phones. Modern cell phones are on their third generation of technology and support features like live streaming media, demonstrating how far the technology has progressed from its beginnings in car-based radios.

The document discusses the history of communication from prehistoric times through the modern era. It describes how early humans communicated through cave paintings and symbols, and how writing developed among early civilizations like the Sumerians and Egyptians. It then outlines major developments including the invention of the printing press by Gutenberg, which allowed mass production of texts; the telegraph in the 1800s; telephones in the late 1800s; computers and the internet in the 1900s. Overall the document traces the evolution of communication technologies and their impacts on spreading information.
What Factors shaped the diffusion of telegraph network?
The document discusses factors that shaped the diffusion of the telegraph network in the 19th century. There was a need for quick and accurate long-distance communication as space and time were problems. Inventions like Claude Chappe's semaphore telegraph aimed to solve this, though it had limitations. The development of the telegraph coincided with the Industrial Revolution, increasing demand for fast transmission of commercial and industrial information. Railroads also drove demand as effective communication was needed to coordinate transportation. The telegraph network spread rapidly across continents within decades as technologies advanced.
EVOLUTION OF THE PHONES
Alexander Graham Bell is considered the inventor of the telephone. He was inspired by an accident to develop a device for transmitting voice over wires. Bell patented the first practical telephone on March 7, 1876. He made the first telephone call later that year between himself and his assistant Thomas Watson. The telephone evolved rapidly from its initial invention due to its necessity for communication. Modern cell phones provide wireless communication capabilities along with additional features like cameras, internet access and apps. Future phones are predicted to have transformable designs and serve as remote controls for various connected devices and services.
From Telephone to Smartphone: A long way in a short time!
1) The document traces the history of mobile communication devices from the telephone to modern smartphones. It discusses how Alexander Graham Bell patented the telephone in 1876, but did not truly invent it, as others had been experimenting with voice transmission over wires.
2) Early telephones relied on existing telegraph infrastructure and switchboard operators to connect calls. While telegraphs required skilled operators and delivered pre-written messages, telephones allowed for spontaneous direct conversations between individuals.
3) The differences between telegraphs and telephones, allowing for immediate responses and tone of voice, helped drive the telephone into American homes and launch the golden age of telephones discussed in later parts of the document.
Telephone Influence on Society
The document discusses the invention and development of the telephone. It describes Alexander Graham Bell as being credited as the inventor of the telephone in 1876, though others like Antonio Meucci had created early prototypes. It explains how the telephone system grew, with AT&T establishing a monopoly that lasted until the 1980s. The telephone transformed communication and connected people regardless of distance.

It discusses the first use of radiophones in the 1920s and the development of the first actual cell phone by Martin Cooper in 1973. It describes the transition from first generation analog phones to second and third generation digital phones that enabled SMS, internet, and media. While cell phones have provided significant communication benefits, their radiation emissions were initially seen as a potential health risk, though no definitive link to serious issues like cancer has been proven.
history-of-radio-broadcasting.pptx
The document provides a history of radio broadcasting, beginning with the discovery of radio waves in the 1860s by Scottish physicist James Clerk Maxwell and demonstrations by others in the late 1800s. Italian inventor Guglielmo Marconi sent the first radio signal across the English Channel in 1899 and the first transatlantic message in 1901. In the early 1900s, radiotelegraphy was developed for ship-to-shore communication. American inventor Lee de Forest developed the vacuum tube amplifier and AM radio in the early 1900s. The first radio broadcast occurred in the US in 1920. Frequency modulation (FM) radio was invented in 1933. Existing laws in the Philippines govern radio broadcasting and provide franchises for radio stations.

The Birth of Telecommunication
Introduction
In 1876, alexander graham bell invented the telephone and filed for patents. However, he was not the only inventor of a device that could transmit speech electronically. There was also another inventor known as Elisha Gray, but because Bell made the first move to patent his invention he is believed to be the sole inventor of the phone and this consequently led to big battle of invention. Alexander was a teacher of the deaf, and his motivation for the invention was to create a device that would transmit messages over the wire intended to help the deaf learn now to speak
.
In the development, Bell began with a phonautograph machine from which he studied the sound waves it draws and could trace the vibrations. He was able to produce electrical waves that corresponded with the sound waves he needed and from there he develop a model that practically demonstrated his ideas
.
With the help electrical engineer Thomas Watford, he was able to the physical model of his ideas. He subsequently incorporated additional ideas in his invention and after being granted the patents followed the global awareness and acceptance of the telephone.
Bell offered his patents to the western union for $ 100000 but had difficulty in convincing the management that the telephone invention was a viable idea. The major setbacks were that the voice signals being sent were very weak, and they grew weaker the distance between the receiver and transmitter is long
.
They did not see the reason as to why anybody would want to use such a device when one can send clearly written messages to any part of the United States. They also did not see the device as ever capable of any improvements on the weak signal to produce a recognizable speech over long distances. Having made substantial improvements to the telegraph, Bells device was of no use to them. It, however, did not take long before they realized that technology was evolving, there was need to embrace change in order to continue being relevant in business and by 1882, Bell was offered controlling interests in western union. It was in 1876 that Bell conducted a successful two-way talk over the telephone between Cambridge port and Boston two miles apart
. The first switchboard was developed. Bell and Watson later formed bell Telephone Company, where the bell was the electrician and Watson, was the superintendent.
By 1880, the bell company had assembled over 30000 phones that were already in use. One year later bell company purchased western electric, and that is how bell gained the controlling interests of Bell Company. In 1884, the bell company expanded its operations to long distances when it opened services between New York and Boston that is 235 miles apart.
One year later, Bell Telephone Company started a subsidiary company called American telephone and Telegraph Company. By 1890, Bell Company had alre.
