Great link Claude. The numbers in the article makes sense for the time when it was written. I strongly doubt that the Internet porn is worth $1 billion anymore and I'm sure Pay-per-View revenues can't be as high as $128 million with all the free porn available this days.
Oh and OP's graphic is clearly PS, quite a few relatively well-known whores admited their earning from making adult videos are less than $100k/year. With average earning per scene being around $1k, only whores working every third day make more than $100k.
