On 1 January 1983, known as 'flag day', the ARPANET switched over from its original protocol to the Transmission Control Protocol and Internet Protocol (TCP/IP), designed by Vint Cerf and Bob Kahn in the 1970s. The protocols allowed different networks to be linked as an 'internetwork', with packets of data routed independently across any kind of connection. The simple, open design could be adopted by any network, from universities to companies. In the 1980s NSFNET connected research institutions, and in the 1990s the network was opened to commercial use. TCP/IP is still the common language of the Internet.
