The combination of a documentary, radio trailer, and print advert effectively promoted an upcoming documentary about sleep. Key elements like the title "40 Winks" and slogan were consistently used across promotional materials. The radio trailer included audio snippets from the documentary and announced air time and channel. The print advert featured the channel logo and an image representing tiredness to illustrate the theme. Together these ancillary texts created a clear and coherent promotional package that aimed to appeal to both educated and young audiences by taking an informative but casual tone.
