As far as I am concerned, the major reason for its popularity is that this advertisement appeals to our emotion. People usually fancy a baby since it is cute and innocent. With various dancing postures by babies, public cannot even expel from the temptation of babies. Evian makes good use of this approach to draw public attention.
Secondly, the background music also plays a critical role to contribute the prevalence. This is a remix version of 'Here comes the Hotstepper', which was originated from Ini Kamoze. It is a type of Reggae music with a strong regular beat. Besides, the name of the song also matches with the action of pedestrians and babies - very skilled dancers. In light of this, audiences' moods are excited by the rhythms so they view the clip repeatedly, making this advertisement well-known.
Last but not least, the manifest message of this advertisement utilizes the mirror effects. As the water is manufactured by pure and natural resource as indicated in the video, people will become energetic and brisk after consuming its products. For example, even the old woman at the end of the advertisement can dance like a peppy baby. Apart from that, Evian plays with words on its slogan "Evian, live young" due to similar pronunciation of those words.
To conclude, the emotional appeal, background music and message of the video clip contribute collaboratively to the popularity of this advertisement.
