The last time I checked, the world’s population was around 6.8 billion. If only 0.1 percent were to visit your website… and if you were to convert only 1 percent of those to paying customers… and they each paid $2 for a Thneed, for example, then revenues would be over $135M. (And everyone knows you could get way more than 2 bucks for a Thneed, which everyone needs!)
