For most of the 19th century, most of the publications and news were written by one person. Writers could express their own perspectives and opinions. However, since the 1880s, Americans started to become interested in some scientific theories and facts which narrowed the ways that writers could express their feelings. The use of technology led to more productivity and control. New tech in the news process has worked to establish a discourse of speed. The discourse of speed has also become stronger and more encompassing over time. The transformation of the newspaper produced a medium requiring a fairly sophisticated team of many different kinds of laborers. Journalists are expected to possess technical skills in computer-based and new media technologies to some extent, placing new demands on journalists now.
