By using a documentary in an advert, it makes out to the viewers that what they are saying is true. To make it believable they will most likely use an expert from the area of expertise that is being advertised. Some people may not take these sort of advertisements on but some do and this when they do it shows this form of persuasion works. An example of a documentary advertisement would be the EA Sports FIFA 10 tv AD. It shows iconic Manchester Un ited players such as Wayne Rooney warming up, excerising, getting ready for a football games. It shwos the reality of what football is and how resalistic the FIFA 10 game is to real life football. To empahahises this they jump from fifa to real life footbsll several times to show how similar it is. It promotes FIFA 10 well as it uses young people of the public to represent how good this game is. By using the icnoic people and the public aswell, it mkaes you think 'wow this really must be a good game'. It influences your decision on whether you buy it or not.
