Mass media can be defined as means of public communication, which is open to all audiences of people living under different conditions in widely different cultures, therefore reaching a great and wider audience. It establishes contact with people at a distance from the media source and from each other. The audience for mass communications is unique to modern society and the main form of mass media is Television, Internet, Radio, and Newspapers. The Internet is the largest WAN (wide area network) in the world.

It was developed by the United States Defence Advanced Research Projects Agency in the 1960s and was initially known as ARPANET. The Internet was designed to be used by companies and Universities doing military research so that they could share information. Since then the number of people who use the Internet, and the services that are provided on the Internet have grown tremendously. Over half of the population of the United Kingdom can now access the Internet. Unlike other WANs, such as a lottery ticket machine network, the Internet is not owned or controlled by any one organisation.

In fact the Internet is made up of many lots of smaller computer networks LANs (local area network) and individual computers connected together by a WAN to enable computer users to exchange information. Computers are linked from cables and telephone links and if the link is broken the message can easily be re-routed. Each small network that is part of the Internet is known as a subnet, this can be illustrated by the system linkage Subnet A, Subnet B, Subnet C, Subnet D. Many academic universities opted to use the Internet so that they could link up their computers throughout the world.

Today many people have access to the Internet and the number of people who use it is growing considerably, the main reason being that it now contains user friendly software, which has packages that help people use the Internet easily e. g. Netscape. The Internet has now become cheaper as companies realise that they can make a great deal of profit if the majority of the society have the Internet e. g. If consumers join the NTL phone line they get the Internet free therefore encouraging a lot of people to get it.

There are many deals that means anyone who has a phone line, a computer and modem can be connected for as little as i?? 12-i?? 15 a month. In addition it now has a faster communication telephone line, which means that communication can reach top speeds, visuals images and sound can be quickly downloaded. Digital communications across ISDN lines allow greater amounts of information to be accessed. Again the Internet has become part of the civilization, as an individual if you don’t have access to the Internet you are seen not up to date. Asynchronous communication, no censors and copyright are examples of digital liberation.

Asynchronous communication is when people are able to communicate with anyone in the world and leave messages for him or her even if they are not there. The advantages are that users can communicate with people world wide at a free or cheap cost. They will always be able to stay in contact, as the asynchronous communication is a reliable system. This will be a great advantage for businesses as they wont actually have to attend meetings in different locations they can just communicate over the system. The disadvantages are that information can be easily accessed people become stalkers and obsessed with the individual.

The user might not be able to send everything required e. g. Email has a memory capacity and you want be able to send packages that are over the memory limit such as audio. No censor, the data that will be available will be impossible for Governments to stop the circulation of it. This theory is positive as people can have full access with out many problems such as people asking for ID. Companies will get more money, as more people are able to watch it. This theory is negative because young children could see inappropriate things, this can have a negative impact on the society which could encourage illegal sex, violence and drugs etc.

Copyright, this will become a thing of the past. Information will be the property of everyone and we will all have access to everything. The advantages is that it becomes extremely cheap and easy to access. More people will be entertained and people that normally can’t afford films can now watch them. However this has an effect on the economy as no money is going into the products therefore stopping the flow of an economic cycle this then effect the company as they lose profit making people unemployed and inflation will increase.
