Early American publishers and printers played a central role in the social, religious, political and commercial developments in colonial America, before, during, and after the American Revolution. Printing and publishing in the 17th and 18th centuries among the Thirteen Colonies of British North America first emerged as a result of religious enthusiasm and over the scarcity and subsequent great demand for bibles and other religious literature. By the mid-18th century, printing took on new proportions with the newspapers that began to emerge, most notably in Boston. When the British Crown began imposing new taxes, many of these newspapers became highly critical and outspoken about the British colonial government, which was widely considered unfair among the colonists.
