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

9. TRANSISTOR RADIO

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.
