He was also one of the major publishers and propagandists in early America, and his audience was profoundly conservative (often in the puritan sense), rural, and poor.

There was no electronic communication of any sort (electricity was barely understood at the time), and best case transit time was around 6 weeks each way, often 8-12 if possible at all. It was also highly seasonal, and still very dangerous.
