The technological differences between the 1950s and the 1990s

Television s - s Init was estimated that 94 percent of families owned black-and-white television sets. Colour television was launched inrejuvenating 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. See Image 1 Television production techniques also developed throughout the decade.

Infor example, a camera mounted inside a car transmitted images of the Bathurst 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 Pay TV enabled Australians to access a much greater range of sport, news, movie and entertainment channels, 24 hours a day.

Radio in the s FM radio began broadcasting in Sydney in 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 the government funded the development of several multicultural radio stations. Advertising s - s Advertising is considered to have had a major effect on encouraging consumption in Australia. The sustained growth of communication forms like television and radio, allowed advertising to extend its powerful influence over Australian culture and society.

From the s onwards, advertising became increasingly modern, sophisticated and targeted. Its forms also diversified - for example, advertising appeared on the internet and in movies and television through careful product placement.

By tempting audiences with a specifically targeted message, advertising helped create desires for a range of goods and services. As well as communicating to consumers that their product will satisfy a basic need, in some cases advertising also works by implying that a product will project other social meanings like 'success' or 'modernity' onto the user.

Telephones in the s Byalmost three-quarters of Australian families had a home telephone. Telephone technology was constantly improving. In the late s, the rotary dial telephone was replaced with a keypad model, called the Touchfone 10, making dialling even quicker.

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. Telephones in the s Answering machines became popular during the s. Answering machines picked up unanswered phone calls and recorded a message from the caller.

They offered particular commercial benefits to small business owners who could not always stay by the telephone to answer calls.

Mobile phones first appeared in Australia in the mid s. The early models were much larger and heavier than today's models, weighing more than half a kilogram.

Telephones in the s During the late s, mobile phones transformed from being a rare, expensive form of communication to something that many people were reluctant to live without.

Mobile phones became smaller and cheaper in the s and their uptake in Australia was rapid. Injust 1 percent of Australians were estimated to own a mobile phone. In this rate had increased to 13 percent and byaround 45 percent of Australians owned a mobile phone.

Mobile phones allowed for greater freedom of movement and changed the way people communicated. People could be contacted anywhere, anytime and borders between activities became blurred, for example, people could stay in touch with work while enjoying leisure time.

Many social groups, especially amongst young people, maintained their connections through mobile phone conversations and text messaging. While they provided a new method of social connection, mobile phones also threatened to socially isolate those without mobile access.

See Image 2 Health effects of mobile phone usage Throughout the s, debate raged over whether mobile phones had a negative effect on human health. Mobile phone handsets emit electromagnetic waves and some people believed that this radiation could injure brain tissue and cause brain tumours.

Despite the concerns, it was not conclusively proven that mobile phones caused brain damage and most people continued to use them.

Fibre optics The s saw a fibre optic cable network established in some parts of Australia. Fibre optics are very thin, transparent strands of glass that can transmit a much greater volume of information than the traditional electrical 'copper' cables.A microwave oven, or a microwave, is a kitchen appliance that cooks or heats food by dielectric heating.

This is accomplished by using microwave radiation to heat water and . Science & Technology in The s. BACK; NEXT ; Was the Eisenhower era the best of times for science, or the worst?

Science & Technology in The s

It's true that the science of the '50s gave us the most awful weapon ever developed. The hydrogen bomb cast the shadow of nuclear Armageddon over the world. power, and social status, and these social differences limit how fair or equal a personal relationship between two individuals from different .

The ss In the later half of the twentieth century change has been very rapid, therefore there are many differences between the s and the s.

Digital modems developed from the need to transmit data for North American air defense during the s. Modems were used to communicate data over the public switched telephone network. A modem sends and recieves data between two computers.

Between the mids and the mids Homewood Brushton underwent a series of development efforts. Sometimes these efforts were complementary to each other, other times they were at odds.

A different set of assumptions and values informed each development effort. Each effort also reflected changes in local and federal policy.
