How do large companies make money off Super Bowl Commercials?

I mean how is it possible they make more than hundreds of millions in new sales worth paying that much for they ad space?

When the cost per 30-second soundbite is $5-15 million dollars and with 25 between all the breaks and some being 90-second commercials, that's like $300 million on the promise of a few more dollars

How does this pay off exactly? It actually is a profitable investment?
