I think you just made that up. According to who?
I read newspapers with movie reviews, play reviews, comics pages, advertising, news analysis, car reviews, industry analysis, foreign affairs analysis, etc etc etc.
Newspaper reporters win Pulitzers for their original research, investigation and analysis.
God forbid if newspapers should ever merely "report the news", it would be a sad day.
Analysis usually is either a summation of another publication (with citations) or is an Op-Ed.
Investigative journalism is pure news.
