People with lower socio-economic status receive information slower than people with higher socio-economic status.  People with lower SES receive information slower because they are less educated compared to people with higher SES; they have less time to spend on reading information (they spend more time on working to maintain living quality), have restricted from some information that the high SES have the right or easily access to, and less access to information. Young consumers of the newspaper are people with lower socio-economic status, they read less, spend less time on reading newspaper and require smaller amount of information compare to the older consumers.  As the people with lower SES reduce time to read newspapers, their social/political knowledge will decrease as the same time which widened the knowledge gap between people with higher SES and lower SES.  People with lower SES tend to gain information from TV, but the information bias to the entertainment than accurate information which make people lower SES learn poorly. 
In Boston in 1690, Benjamin Harris published Publick Occurrences Both Forreign and Domestick . This is considered the first newspaper in the American colonies even though only one edition was published before the paper was suppressed by the government. In 1704, the governor allowed The Boston News-Letter to be published and it became the first continuously published newspaper in the colonies. Soon after, weekly papers began publishing in New York and Philadelphia. These early newspapers followed the British format and were usually four pages long. They mostly carried news from Britain and content depended on the editor's interests. In 1783, the Pennsylvania Evening Post became the first American daily.
