This advertisement by Cadbury in 2007 was launched to promote Cadbury dairy milk brand chocolate after a series of public relation blunders and product recalls. It quickly became one of the most talked about advertisements of the year. The gorilla advertisement didn't follow cliché advertising techniques and it didn't target a specific audience. Instead it established connections between random viewers from all over the world and gave them something to talk about. This was done though word of mouth and social networking sites. the advert was uploaded to YouTube where it received 500,000 views in its first week. This is an example of extreme viral marketing, a technique that uses pre-existing social networks and technologies to increase brand awareness.
The advert also uses a song by Phill Colllins - 'In the air tonight' which is a well known hit from the 80s. Familiar music has been found to increase the memorability of an advert, as shown by Alexomanolaki et al, in their 2006 study whereby music proved to reinforce the perception of the advert for both musicians and non musicians. Due to the adverts randomness it is seen to be quite funny, a review by Marc Weinberger and Charles Gulas (1992) stated that humour attracts attention, does not harm comprehension, increases liking and can increase persuasion making it an effective advertising technique.
