Pluralism

In what ways do I agree with Pluralism?
To a certain extent i agree with pluralism as society, for example the media have choices within the market for example with magazines. Also if we look at superstores there is now a wide range of places to go however there is a tesco preety much located everywhere therefore people-consumers are drawn towards them. Similarly, television have choices of channels to watch however if one person owns these channels then they will provide the audience with the same values as a result there is really not much choice for example Murdoch. This shows that there really is not a pluralistic society......MR BUSH WHAT IS FOURTH ESTATE BECAUSE I DO NOT THINK WE WENT THROUGH THIS BIT....
