Have you noticed how the news on TV only ever covers the three main parties? Occasionally you hear the odd bit about another party, but that's about it. Fair enough if you want to vote for any of the main parties, but what if you want to hear about the others? To me it looks like the three main parties have very similar policies to each other, so there's not exactly much choice between them. If you don't like one of them, you're not likely to want to vote for the other two either, they're one and the same. It seems to me the reason that news programmes focus on these three is because they don't mind which of them gets into power, because their policies are so similar that they will be equally as benificial (or at least don't pose a threat to) the companies who distribute the news, the people employed in the news industry and so on.
The worst bit is when TV journalists start putting their opinions across during news bulletins. They're meant to be impartial! The BBC seem to be particularly bad at this. Which is ironic seeing as they came up with the concept of public service broadcasting. I thought that at least part of the point of public service broadcasting is to inform the viewers? Even more frighteningly, it isn't what we are told that is the problem, it's what we are not told that stops the viewers from being able to make properly informed choices. Of course it can be difficult to tell whether or not you are being given all the information, because the less you know, the less you think there is to know.
