During The World Summit on the Information Society (WSIS)1 came up with the following working definition of Internet governance:
Internet governance is the development and application by governments, the
private sector, and civil society, in their respective roles, of shared principles,
norms, rules, decision‑making procedures, and programmes that shape the
evolution and use of the Internet.
