This arrangement continued until 2010, when the increase in HD content saw several changes. 2010 had been the BBC's internal deadline for the majority of new content to be produced in HD and as a result the broadcast space was fast running out. As a result, on 3 November 2010, BBC One HD launched as a separate simulcast of the channel and at approximately the same time, BBC HD's broadcast hours were extended to twelve hours a day. The channel now catered for the programming of the BBC's channels other than BBC One.
