I agree with answer 3 more than answer 2 because #3 points out that ALL news is biased in some way. But I don't really agree with her conclusion that this means where we get our news matters.
If all news is biased, then where we get it (as long as it is factual) does not matter.
What really matters is whether we are able to understaned the bias held by any particular news medium.
One thing about the changes in the industry that does matter, in my opinion, is the tendency toward shoestring budgets and cuts in news staff. We can live with biased news, but if news organizations cut too much staff, there won't be any news at all (or not enough). That's a much bigger problem.
Another thing is that I would say that any medium that we read is better than any medium that we watch. TV news is going to be more biased towards events with exciting visuals than newspapers, magazines, or websites.
Overall, I'd say that ideological bias doesn't matter as long as we're aware of it. Bias towards exciting stuff (as well as cuts in staff) do matter because they reduce the overall quantity of news that is available.
