One thing that has changed is that the Evening News on the big three American broadcast networks used to be pretty much a straight reading of the news by an anchorman. Now you have news "analysis" programs, especially on the cable networks. These tend to be strongly opinionated right or left, and include a lot of guest speakers who are not journalists, and who are also politically opinionated. Because of the viewership these shows attract, traditional media outlets are now also less straight news and more opinion. I generally feel it's pretty clear when I'm listening to an opinion show versus a news show, but I'm not sure how many others do.
