Article: Tracking the iPhone’s bubble of hype
Article: How does this work?
From the first article...
"Google Trends is a powerful tool. It has been used, most famously, to monitor influenza outbreaks by tracking flu-related Google searches — a epidemiological early warning sign that turns out to be more prescient, by two weeks, than the U.S. Centers for Disease Control’s surveys of 1,500 hospitals. (Google explains its methodology here, with a link to an article in Nature.)"
Makes sense that tracking what people are searching for in real time could be an early warning of flu epidemic but who would have thought that it would be better than the U.S. CDC's method by two weeks.
Interesting... I wonder what other nuggets are out there.
