The BBC also broadcasts edited Top Gear programmes on its international BBC World TV channel. Episodes are shortened from their original length of one hour to 30 minutes, often leaving dangling references and inconsistencies. Additionally, the original transmission order is sometimes not adhered to, so references to un-aired events are common. The only footage specially shot for the international version is for the end of each episode, when Clarkson bids his goodbye to BBC World viewers, instead of BBC viewers.
