Google Flu Trends (GFT) was a web service operated by Google. It provided estimates of influenza activity for more than 25 countries. By aggregating Google Search queries, it attempted to make accurate predictions about flu activity. This project was first launched in 2008 by Google.org to help predict outbreaks of flu. Google Flu Trends stopped publishing current estimates on 9 August 2015. Historical estimates are still available for download, and current data are offered for declared research purposes.
