Advertisements, on the outside, seem simple and straightforward. The advertisers create something that showcases their product so that you want to buy it. Simple right? Not exactly. For decades, advertisers have been inserting things into advertisements to make you feel specific emotions, to which you are unaware the advertisement is actually doing, regarding the product(s) being shown. Things like car and sport advertisements tend to create a sense of excitement and thrill to emphasize their products, while beauty and decoration advertisements often exhibit feelings of calmness and serenity to get their point across.
This advertisement by Apple is no different. Apple is clearly trying to portray a sense of fun, excitement and enjoyment in this advertisement. The goal of the advertiser is to make viewers feel like buying/using an iPod will make them more happy, more excited, more fulfilled. Also, the advertisement prominently displays people wearing up-to-date, "cool", clothing. This, along with the focus on solid black, white and a single bright color, also adds to the effects of fun and excitement.
