- A 60 second Super Bowl ad goes for $8 million, so $80 million over 10 minutes. 
- 111.5 million people watched the last Super Bowl representing 1.59% of the worlds 7 billion population, or 1 in 62.5 people. 
- $80 million x 62.5 = $5,000,000,000. 

So help me if one person chimes in with /r/theydidthemath I will lose it.
