The State of the Fourth Estate

What is 'the Fourth Estate'?
The fourth estate is the press; it was the most important estate. It acted as a check on abuses of power by the other three estates, by holding them accountable to the electorate and providing information to ensure democracy is allowed to operate efficiently.
Is new media technology responsible for the decline in newspapers?
Yes it is, with new media technology, there are easier ways and cheaper ways to read the papers and the information they give. Such as the internet, people can go onto the internet form anywhere and read papers online, which is free of charge. As well as 24 hour news TV, which constantly.
What does it mean "maybe the internet is already the cyberspace of the fourth estate"?
It is said the internet is now the main power in media technology, providing us with whatever we want whenever we want it. This means that although the internet has caused the decline in newspapers by providing faster, cheaper access (anywhere in the world) to stories developing around the world, the original purpose of the fourth estate can still be carried out by these new media technologies.
