Emerging communications media and information technology create unprecedented opportunity to improve people's lives. The Markle Foundation works to realize this potential by accelerating the use of information and information technology to address critical public needs, particularly in Health and National Security. We collaborate with innovators and thought leaders from the public and private sectors whose expertise lies in the areas of information technology, privacy, civil liberties, health, and national security. This has enabled Markle and our collaborators to offer comprehensive recommendations for sectoral change, many of which have become law through acts of Congress and by executive order.
