A documentary uses many persuasive languages and ways in which draw in the viewer to buy the product which is being advertised. Documentaries make many claims which can either be true or false, but no matter what they claim they explain and give reasons on why it may/might be true. Using an expert from the area the product is being advertised, is always helpful for the consumers as they will tend to believe it more.
The Colgate advert is a prime example of a documentary advert; it is an advert for toothpaste which helps get rid of a list of things such as;
v Cavities
v Gum Problems
v Plaque
v Tartar
v Bad Breathe
v Staining
v Sensitive Teeth
v Enamel Erosion
It makes many scientific claims about the product, and the person explaining all of this when seen on screen sounds like he knows what he is talking about as if he is an expert which also is persuasive for people to buy the product as it seems more believable. This advert is aimed at many people from mums, to people with sensitive teeth, smokers and many more. It gives off a technique of promise of benefit.
