The combination of the documentary and ancillary texts (radio advert and poster) is effective. Both the documentary and radio advert use the same music and voiceover to create a specific mood and inform audiences about the content. The poster was also carefully designed based on research of similar shows. It uses a ghostly green background and images of people to suggest the documentary is about paranormal investigation and participatory. The channel logo informs viewers where it will air. Overall, the ancillary texts complement and reinforce the key elements of the documentary to promote and market the show effectively.
