Ten years ago, writes Kelly Henning from the Bloomberg Philanthropies Public Health program in the Health Affairs blog, the world was a different place when it came to tobacco. Fewer than twenty developing countries in the world had even one strong tobacco control policy in place. The tobacco industry was beginning an aggressive ramping up of nefarious activities to grow their market share in vulnerable developing countries. And although advocates for tobacco control measures had a major public health victory in passing the Framework Convention on Tobacco Control, the world’s first public health treaty, little financial or technical help was available to support countries that wanted to put life-saving, proven tobacco control policies in place. Early in 2007, the tobacco control landscape was changed dramatically when Michael R. Bloomberg, then in his second term as mayor of the City of New York, donated $125 million through his foundation, Bloomberg Philanthropies, for a two-year commitment to reducing global tobacco use. Now ten years and a total of $600 million later, Bloomberg recently committed another $360 million over six years to this life-saving work, bringing his total financial commitment to nearly $1 billion. In that time, nearly 100 countries worldwide with a total of more than four billion people have passed at least one strong tobacco control law—and fifty-nine of these countries with nearly 3.5 billion people have received Bloomberg support.
