Ultimately, I think that the media should only have a major role, if it is unbiased and not controlled by the government, which does not seem likely.
I think you can use it to expose only certain things, i.e. not just to "expose" a celebrity kissing somebody; only in a way that can really help society, like maybe the media finding and stopping a politician from doing bribes (even though that always happens anyways).
I think it should actually not educate, as I think that only findings from uncontrolled speech and actual journals and work should be teaching. It can be good and all, but sometimes, depending on who controls it, like in the case of a dictator like Stalin, can drastically change what is actually the truth, and everyone knows this already happens all the time.
So ultimately, it should just be to inform on issues that need to be dealt with.
Mhm.
