Here is what this analysis found. Only 3 percent of the reports about Trump that aired on NBC and CBS were positive, while 43 percent were negative and 44 percent were neutral.

On “Special Report,” the Fox News program that most closely resembles the evening network news, 25 percent of the reports about Trump were negative, compared with 12 percent positive and the remainder neutral. In other words, even the conservative-leaning Fox News featured twice as much bad press as good press.

The networks differed in their emphases. Fox News focused on personnel decisions in the new White House, and coverage of that issue area was more positive than negative by a ratio of 2 to 1. Another bright spot for Trump was Fox’s coverage of economic news: There was mostly positive coverage of the new president’s initiatives that are intended to strengthen the international competitiveness of U.S. business.
