Yesterday the Pew Research Center released data on the news coverage of Typhoon Haiyan — a disaster that has killed at least 4,000 people — and the bungled Obamacare website roll-out. Comparing 20 hours of news coverage over four major U.S. channels, they found dramatic differences. The data below shows the hours and minutes spent on each topic at each channel (red = Obamacare, yellow = the typhoon).
