I agree with your overall point but you're wrong about this. Journalists most certainly do influence "news". For a start they decide, and therefore censor, what articles are reported and how they are reported. There are several reasons for that, including commercial ones. Anything that doesn't suit their agenda is ignored at worst or pushed down the agenda at best. The English premier League is a classic case in point. Despite the BBC claiming to be strong on diversity and fairness, that certainly doesn't extend to Scottish football. The newspapers and TV can and do influence viewers' and readers' knowledge and preception of games by cutting out incidents they don't want shown or by highlighting those that they do. That influence also extends to general football coverage.
Deep down, I don't have any objection to most of it especially by private organisations, as I don't have to pay for it if I don't want to do so; don't have to read or view it; and as long as they don't say its unbiased and factual. I do however have issue with the BBC as its funded by taxpayers' money and I have no choice but to pay for it.
Apologies for the rant.
