From Forbes' site:
http://www.forbes.com/2006/10/23/tech-media_06deadcelebs_cx_pk_top-earning-dead-celebrities_land.html
really not relevant... it says something, but its not that meaningful. Sure it compares 2006 dollars and activity for 2006. Its also misleading
NEWS FLASH!!!!! Elvis has been dead for 30 years.
Its kinda like comparing a model t ford to a horse. sure they were both transportation but a lot happens in 30 years.
Elvis' lifetime earnings?? Elvis's market penetration?? Elvis residuals?? Elvis's lifetimes earnings equated to 2006 dollars? His estate earnings? residuals? His future? I know - flippin @ Wendys.
I am sure once one looks at theses other factors,,,,,, the King will still be the King and characters like Cobain might be contenders, weak ones.
