Who We Support

Tobacco Watcher is designed to make media monitoring easier and more effective, thereby informing and improving global tobacco control. Tobacco control advocates, investigators, and students spend can spend hours searching through the same news articles to find tobacco-related content they care about. Tobacco Watcher now does the searching for you.

Moreover, by classifying tobacco-related media by content and location, in twenty-three languages, you can explore far more of the tobacco control landscape than was previously possible. As a result, advocates, policy makers and researchers can spend much more of their time analyzing instead of searching for data.
