THIRD EVOLUTION OF MEDIA
Subject: Media Information and Literacy

1. ELECTRONIC AGE

2. ELECTRONIC AGE Also known as “The rise of Global village” with the tap-tap-tap of the telegraph. MCLuhan insisted that electronic media are retribalizing the human race. Instant communication has returned us to pre-alphabetical oral tradition where sound and touch are more important than sight.

3. Telegraph (1836) Was made in the year 1836, it marked the arrival of instant long distance communication .

4. Eniac (1947) One of the world’s first digital computers, is turned on after a memory upgrade. It will remain in continuous operation until October 2, 1955.

5. Transistor (1947) Transistor is a device that regulates current or voltage flow and acts as a switch or gate for electronic cignals .

6. The electronic age is also known as the information age or the digital age. It began around the 1970s and continued till the present day. This is  a period of transition from traditional industry to an economy based on information computerization .

7. ELECTRONIC AGE (1930s TO 1980s) The invention of the transistor ushered in the electronic age. People harnessed the power of transistors that led to the transistor radio, electronic circuits, and the early computers. In this age, long distance communication became more efficient.

8. ELECTRONIC AGE (1930s TO 1980s) Example Forms of Media Transistor Radio Television (1941) Large electronic computers Mainframe computers – i.e. IBM 704 (1960) OHP, LCD projectors

10. TELEVESION 1941

11. Mainframe computers

12. The electronic age began in the 20th century when digital computers were built around electrical switches and electromagnetic relays. This period is so-called because the mechanical devices invented used electrical switches for their control.

13.  Lastly, the Electronic Age, an era of instant communication and a return to an environment with simultaneous sounds and touch. It started with a device created by Samuel Morse’s invention of the telegraph and led to the telephone, the cell phone, television, internet, DVD, video games, etc.

14. This ability to communicate instantly returned us to the tradition of sound and touch rather than sight. Being able to be in constant contact with the world becomes a nosy generation where everyone knows everyone’s business is everyone else’s.
