The series introduced a new logo, which was announced in October 2009. According to the BBC, it was the eleventh version of the show's logo. According to Moffat, the "DW" insignia in the shape of the TARDIS was "something really new". The logo was incorporated in a new title sequence, which was not revealed to an audience outside the BBC until the first transmission of "The Eleventh Hour"; previous press screenings and previews had used a variant of the previous sequence. Moffat wanted a new version of the theme music, and composer Murray Gold wanted it to "sound a bit reckless". The new version, composed by Gold, incorporated an electronic-trumpet melody and a faster tempo. Some fans disliked the new theme, and the BBC had received 70 complaints by 18 April 2010. A Doctor Who spokesman responded, "The arranger has made alterations to the music four times since 2005, so change is nothing new. It is important for the regeneration of the show to keep revisiting the score while always retaining the haunting and ground-breaking essence of the original".
