Evolution of the phone: From the first call to the next frontier. (2014)
Zigterman, B. (2013)
This presentation was built using credible and reliable sources, as determined by Metzger's Credibility Checklist format (Metzger, 2007). In order to be deemed credible, the source must meet 3 out of the 4 criteria:
Site is free from errors, and can be viewed offline.
Information provided for author.
Defines whether information is free from opinion, and is fact based.
Depth of information on site is updated regularly, and date stamp is available for recent updates.
Each source was measured against these criteria, and deemed credible and reliable. A full reference list of these sources can be viewed in APA formatting at the end of this presentation.
Television is the system with which light and sound signals are converted into electrical waves. This produces light rays and audio sound which are sent via wires to display a moving picture on a screen.
Philo Taylor Farnsworth performed the first successful electronic television transmission on 7 September 1927. Australian television followed sometime later with the first broadcast in 1956, and colour television being introduced in 1975.
Television has progressed at a fast pace since its first introduction. Many options are available, new technology allows us to pause, rewind live television, record and series link programs; ensuring that we never miss a thing!
Television enabled the witnessing of major events of the last century. It has become a fixture in every home. When used judiciously, it is a medium with which to educate, entertain, and instruct society.
This presentation acquaints us with the evolution in technology; primarily telephones, music devices, televisions, computers and internet. We live in a digital age where the development of these inventions has revolutionised all factors of our day to day lives. This is evidenced clearly in communication, education, health care, entertainment, recreation, travel, and economic fields, to name a few. By bringing the world to our fingertips, technology has enabled us to transcend our natural limitations, and enhance our lives in today's fast paced, and multifaceted environment.
The telephone is an electronic instrument that processes and transmits voice and sound, through wires and transmission media, over a distance. It allows for two or more users to communicate with each other from separate locations.
Alexander Graham Bell spoke these words into the first patented telephone to his assistant, "Mr Watson, come here, I want to see you." (Belle, 1876).
Telephone technology has changed substantially today; land phones (requiring a stand still point of attachment) have given way to mobile phones (can be used anywhere at anytime) which use radio network for coverage.
The telephone has become an all purpose tool used to communicate effectively and efficiently, to entertain, for security, as an organiser/calendar, and a computer. As well as being an important tool for communication in the modern world today, telephones now also facilitate instant access to the online digital world.
The first recording devices were instruments to capture and study sound waves. Magnetic recording and tape recorders replaced phonographs and optical recording methods. Innovations led to multi track recording, stereo sound, digital audio and media free forms such as MP3.
Firstly, sound recording utilised mechanical devices like cylinders (phonograph) and stylus (gramophone). Then electro-magnetic, multi-track, stereo sound and digital recording made music portable. The music player technology developed into gramophones, LPs, tapes, CD players, streaming services, docking stations, smartphones, tablets and iPods.
In recent years the Apple iPod revolutionised the music industry with high storage capacity and instant access, compared to earlier devices. Though the iPod was the favoured choice of music device, today, our preference has slowly shifted towards smart devices (e.g. smart phones, tablets etc). These forms have a constant internet connection and have enabled us to download and stream music at our convenience, thereby re-shaping how we access entertainment.
Modern Music Devices
The internet is a global computer network connected by servers and routers, almost anywhere in the world. The Internet was developed in the early 1960s by researchers sharing information and data for military and scientific fields (A brief history of the internet, 2012).
The modern internet owes itself to the Pentagon’s Advanced Research Projects Agency Information Processing Techniques (ARPA) (Taylor, R 2015). It was here that Robert W. Taylor developed it into the multifunctional tool it is today, building on his concept that the initial internet was not interactive enough. Internet has evolved into a complex and powerful multidisciplinary tool bringing the world literally to our finger tips thereby us from geographic limitations. (Dentze, Z (n.d). It has revolutionised all areas of our life from: social, education, medical, media, and consumer services etc.
. Internet means:
• No posting letters- send an email or instant message.
• No watching mainstream television - download your favourite shows.
• No 6 o’clock news for the day’s events – instant updates on information and social media sites.
• No searching books in the library- find it online.

The first mass-produced television set
Jason, G.A (2015)
There has been a huge progression for the earliest design of the computer in the form of a calculator in 1822 by Charles Babbage, to our modern desktops, and laptops that we see now. Today, computers have massively impacted our lives in communication, in education, military, workplaces, utility and health care. This is by facilitating contacts, enabling access to digital information, facilitating travel, complex operations of services, data storage etc, instantaneously. The computer is considered to be one of the incredible inventions of all time and it will continue to be the same for years to come.
Computers are electronic machines that perform tasks according to the instructions given to them. There are various types of computers ranging from super computers to personal computers and laptops. Prime uses of computers are to store and retrieve data, and track projects and activities.
HISTORY OF THE INTERNET. (2014).
Through the use of Prezi, we aim to provide brief and succinct information on various forms of technology (telephones, music devices, television, internet, and computers), and how they have evolved and impacted our lives today.
