Super Bowl ads are a great study in effective marketing.
If successful, they drive incremental sales or website traffic. Over time, they also feed brand power. During these tough economic time, though, driving sales NOW is the key to a good ad.
At the grocery store last night, stopping in to get some milk, I grabbed a bag of Doritos. Now I know why. Their ad was funny, make the productive attractive and showed an intelligent sense of humor.
In short, it had a high likeability factor — the secret to great marketing!
