Romes first season originally aired on HBO in the United States between 28 August and 20 November 2005, subsequently being broadcast on the United Kingdom's BBC Two between 2 November 2005 and 4 January 2006, and on Rai Due in Italy between 17 March 2006 and 28 April 2006.
A "sanitized" version of the first series of Rome - with toned-down nudity and violence - aired on Rai Due in Italy, garnering only a meager 10% audience share.
