Codes and conventions of Radio Trailers

• Ended with a different voice explaining when and where it will be shown.

• Sound effects, sometimes used to grab attention.

• Uses a voice over that we assume is from the documentary. The voice over creates expectations for the listener e.g. a man's voice on the radio advert means that there will be a male voiceover on the documentary.

• Take extracts from your programme, in order to hint what will be in the programme and create the link.

• Make sure the beginning is clear, so the audiences attention is bought.

• Music bed that relates to the topic or theme.
