Using talking heads in advertisements shows the general public that they are using real epople to feed back on the product they are trying to sell. This helps the audience relate to the people in the adverts because they are normal everyday people and are in the same situation. If the results at the end of the advert turn out to be good, then the suidence are more likely to beleive it, so it must be true, becasue they are saying that it is.
An example of a talking heads advertisement is an Envirofone advert from 2009. It shows many different people talking about how easy it is to get money for your old mobile phones. They all look enthusiastic and excited about the service and as they are normal everyday people, it is made more beliveable.
