3. By 1973, almost three-quarters of
Australian families had a home
telephone. Telephone technology was
constantly improving. In the late 1970s,
the rotary dial telephone was replaced
with a keypad model, called the
Touchfone 10, making dialling even
quicker.
STD (subscriber trunk dialling) was
joined by international subscriber
dialling (ISD) in 1976. ISD took
Australians one step closer to the rest of
the world, enabling callers to dial
directly overseas, rather than having to
call an operator to connect them.
Initially available to Sydney residents,
ISD had spread across Australia by the
end of the decade.
4. FM radio began broadcasting in Sydney in 1974.
FM radio employs technology that provides a much
higher quality, less distorted sound than AM
broadcast.
FM radio also created space on the airwaves for
a greater variety of commercial stations, as well as
small niche stations. In 1975 the government funded
the development of several multicultural radio
stations. Two of these stations, 2EA in Sydney and
3EA in Melbourne, were eventually combined to form
the Special Broadcasting Service (SBS).
5. In 1975, Bill Gates and
Paul Allen from a
partnership called
Microsoft.
Like most start-ups,
Microsoft begins small, but
has a massive vision – a
computer on every desktop
and in every home.
During the coming
years, Microsoft begins to
change the ways we work.
Microsoft is now one of
the biggest companies in
the world.
6. In 1975, it was estimated that 94 percent of families
owned black-and-white television sets.
Colour television was launched in 1975,
rejuvenating interest in the medium. Within three
years of its launch, it was estimated that 70 percent
of households in Sydney owned a colour television
set.
Television production techniques also developed throughout the decade. In
1979, for example, a camera mounted inside a car transmitted images of the
Bathurst 1000 car race directly to viewers at home. This gave viewers a
much more exciting, first-hand television experience.
Satellite or 'pay' television was introduced in 1995. Pay TV enabled
Australians to access a much greater range of sport, news, movie and
entertainment channels, 24 hours a day.
7. BETAMAX VIDEO STANDARD
(1975)
Betamax was a analogue videocassette which
allowed the recording and playback of video. Betamax
was developed by Sony and released in japan on May 10th
1975.
The name ‘BETA’ comes from the fact that when the
tape ran through the transport, it looked like this Greek
letter beta (β). ‘Max’ was to suggest that the videocassette
performed at maximum capability.
8. The first personal computer was invented
in 1977 by Intel anAd the computer was
called the INTEL 4004. The personal
computer was for recording data, playing a
variety of games and calculating data. As
time passed on the personal computer got
smaller and had new features due to
technology advancements. Later other
companies started to make computer such
as Apple and Commodore Pet.
9. The first cellular mobile phone was invented
by Bell Labs and licensed by AT&T in 1977. Other
phones were licensed by AT&T before but weren't
mobile. Before the cellular mobile phone was
invented the federal communications service had
to agree to take action before the phone could be
sold. When the phone was able to be bot it became
really popular and many house holds carried the
phone. As time passed the phones became smaller
and different companies stepped up and created
phones.
