In 2006, along with Tim Berners-Lee, Nigel Shadbolt and Daniel Weitzner, Hall became a founding director of the Web Science Research Initiative (WSRI). Now known as the Web Science Trust, the WSRI was originally a collaboration between the University of Southampton (ECS) and MIT (CSAIL) which aimed to coordinate and support the study of the World Wide Web. The WSRI's activities helped to formally establish the concept of Web Science, and Hall is now Executive Director of the Web Science Trust.
