With the invention of the telegraph in 1844, news became even more accessible. By 1860, the U.S. had around 2,500 newspapers and over 50,000 miles of telegraph wire. Between 1861 and 1865 the North had approximately 350 correspondents and the South had approximately 150 correspondents who reported on the war. Correspondents were usually paid by the story. Freelance writers were paid between $5 and $10 per column. Sometimes the stories were more sensational than fact. Even though they were protected by international conventions of armed warfare, history shows that it was a dangerous job since they were often considered targets. Army officers weren't happy with correspondents because they would report troop movements. Some were also accused of being a spy.
