“No one man should have all that power”
— Kanye West
We’ve all heard that the media business is cutthroat. In books, or movies or music, a few dominant artists tower over the rest. These superstar directors and writers and musicians sell millions of units while their peers languish in obscurity.
I wondered, are all forms of media equally competitive?
To find out, I scraped the internet for as much media data as I could find¹. To my delight and surprise, whenever I ordered things by the biggest winners, the same pattern emerged. It’s called power law, and you can see it below.

Media Data and Plots
The New York Times web API³ provides a list of fiction best sellers from the last 7 years. If we measure success by weeks on the list, we can compare the most and least successful books.
Below are plots organized by novel, author, and publishers. I also show the top-20 results in each category, both for fun and to prove that the data is correct.
