If you have a problem with the BBC’s news output, spend a week in the US and try watching news over there. You can watch CNN for a whole day and get less information than watching 5mins of BBC news. When you listen to R4, the density of information gets even better, especially some of the late night news where they get candid interviews with major players who aren’t high profile, but have deep insight into current issues, and will talk without spinning or trying to influence peoples opinion.
For a democracy to function effectively, the population has to be educated. The BBC does a very good job at doing that.
Look at UK newspapers on both side of the political fence, who basically blatantly went all out to get people to vote how they wanted on the run up to the election. Most of the output from the Telegraph / Guardian in the weeks leading up to the election was a disgrace. Do people really want to pay for a paper who tries to tell them how to vote? Contrast that with how the BBC behaved.
Some of the other BBC output, like the R4 series on the Magna Carta is just priceless. That content will be relevant for decades.
The BBC is one the positive things which define the UK to the rest of the world as a progressive country. If the Conservatives start attacking it, I for one will be fighting very hard to resist.
