By the American Revolution, newspapers were getting closer to our modern perception of them. But for the hundreds of years between their ostensible invention in Germany and the late 18th century they were quite different. Many only reported foreign news (in part to avoid domestic topics that may have been more sensitive). They offered very little in terms of editorial. In France, one particularly dull one was granted a monopoly, stopping competition.
Andrew Pettegree's Invention of the News covers this in much greater detail: https://www.theguardian.com/books/2014/feb/19/invention-news...
One other interesting anecdote from the book: For quite some time, the identity of who was conveying the news was paramount. A nobleman's wild story would be given more stock from contemporary audiences than several eyewitness accounts from commoners.
