BBC HD has used the same logo since its launch in May 2006. It consists of the BBC logo with a fourth square which has been turned to become a diamond.
In its short history, BBC HD has gone through three different presentation packages. In July 2008, launch ident was replaced by an elaborate computer-animated ident featuring the HD logo rising from from the sea. This ident was shortlived, and was replaced by a set of live action idents in March 2009.
In 2011, it was proposed that BBC HD would be closed down and replaced by a full time simulcast of BBC Two in 2012.
