Scripts are used in radio broadcasting to guide presenters and ensure the show runs smoothly. They prevent mistakes by listing what should be said and when. Scripts are written for the ear rather than the eye, using language that allows listeners to feel like the presenter is speaking directly to them. Different genres have different scripting conventions - music shows include song sequences, while documentaries may have full scripts and some unscripted interviews. Stations also have their own styles that are reflected in the scripts, such as the use of informal language on local stations to connect with listeners.
