The [Apple Store/iPhone] television ads are effective because in thirty seconds they paint a picture of a problem and offer a solution. For example, in one ad for an app called Shazam, a narrator says, "You know when you don't know what song is playing and it's driving you crazy? With the Shazam app, you just hold up your iPhone to the song, and within seconds you will know who sings it and how to get it." The taglines are always the same: "That the iPhone. Solving life's dilemmas one app at a time." The ads prove that establishing problems and offering solutions need not be time consuming. Don't spend too much time getting to the punch line.
