As far as I know, it’s in the mission of most of these to give an unbiased report on what is happening in the world and inside the country. In practice, there may be influence by powerful politicians, but for these news outlets to spread government propaganda would constitute corruption.

I know that the BBC in the UK, SVT in Sweden, the ABC in Australia go to great lengths to listen to both sides, whatever they may be, to a fault. They are often criticized for giving minority views too much coverage for this reason, and rarely for saying what the government would want them to say uncritically.
