The browser was released outside CERN in 1991, first to other research institutions starting in January 1991 and to the general public on the Internet in August 1991.
Khou Yang was 47 years old when Invasion of Iraq: In the early hours of the morning, the United States and three other countries (the UK, Australia and Poland) begin military operations in Iraq.

This early stage of the war formally ended on 1 May 2003 when U.S. President George W.

U.S. military forces later remained in Iraq until the withdrawal in 2011.
