The BBC began simulcasting the channel overnight on terrestrial channel BBC One with the launch of the channel , ending the tradition of a closedown but at the same time effectively making the service available to many more viewers . In the early 2000s , BBC Two also started simulcasting the channel , although the weekend morning show '' Weekend 24 '' had been simulcast on the channel in the early days . During major breaking news events , the BBC News Channel has been broadcast on BBC One ; examples of special broadcasts include the 11 September 2001 attacks , 7 July 2005 London bombings , the capture of Saddam Hussein , and the death of Osama bin Laden
