I think newspapers, pamphlets, and novels were very influential in creating a shared culture throughout the British Empire because they served as the official means of communication to convey the information the monarchy needed to convey to all the regions of the empire. The British government was very careful in communicating just what it thought would be convenient for the people of the empire to know. Nothing more, nothing less.
I think present-day forms of international media, like television shows and websites, can be compared to the printed word in the eighteenth century in that represent what we know as mass media. They are the ones that report the news, have a group of reporters that investigate and inform about the things that are happening and affect society, the way newspapers did in the 1700s.
It was through the media, that people knew what was going on in politics, economy, and social life. Similar situation as what modern media does in today's society.
