This is an advertisemnt for the soft drink Pepsi. It shows the super star Britney Spears who is a very famous American singer and especially popular among the young generation. This is a typical technique of company owners to associate famous celebrities with their products to increase sale. She is shown as to endorse the product, and presents a rock star image to attract audience. They are trying to propogate the idea that super stars like her, drink their product, and we should too. Not only will her fans go for it but the glamour image shown in the ad will attract other people too. thier tag line "Ask for more" sells a promise that once we drink Pepsi we will be wanting more.
