I determined that using Newssift, an "intelligent search tool" developed by the Financial Times Group. Among the neat things Newssift does is assign a "sentiment" -- positive, negative or neutral -- to each of the news articles it turn up. That allows you to gauge how the coverage of a particular topic shifts in tone over time.
