Codes and conventions of Radio Trailers

-There is a different voice at the end of the trailer to tell us extra information for example, the scheduling of the programme
-The slogan from the documentary is used in the radio advert to link them together
-The voice over creates the listener's expectations for example a man's voice on the radio means that there will be a male voiceover on the documentary
-The same voice is used in the radio as in the documentary
-Sound effects are used to engage the listeners
-The music bed used connotes the theme or topic
-Extracts from the documentary should be used to link the radio with the documentary
-The beginning should be clear to grab the audience's attention
Because our documentary is scheduled on Channel 4, we arent able to schedule our radio advert on any BBC radio, so we would have to schedule ours on stations like Radio City 96.7 and Buzz fm.
