In 2009, Ed Bennett of the University of Maryland Medical Center began collecting data on how hospitals are utilizing social media technologies. The list, found on his blog, Found in Cache, has become a globally referenced resource for individuals seeking to understand how hospitals are leveraging digital and social technologies.
In December 2011, with the assistance of Silja Choquet of Why Dot Pharma, Bennett published a visuailization of the data in the list utilizing Google Maps. (See below for a sample image).
