Writing Success = Netflix?

 So it seems from The Atlantic's THE RISE OF MUST-READ TV: How your Netflix habit is changing contemporary fiction by Alexander Manshel, Laura B. McGrath, and J. D. Porter

We see evidence of the adaptation effect in other measures of literary success as well. We compiled a list of about 400 21st-century novels that met certain criteria—inclusion in top-10 best-seller lists, critics’ picks, publishers’ comp titles, and so on. Within this group, a novel that becomes a show will receive about four times as many ratings on Goodreads.com as a novel that has never been adapted to TV or film. (Film still has a bigger effect, boosting a novel’s Goodreads ratings more than 1000 percent; TV nonetheless dramatically improves the fortunes of a novel.)

Well, I thought this might be a thing when I was still in prison.  We had guys bootlegging Boardwalk Empire and The Handmaid's Tale and a ton of other stuff from the streaming services,and it seemed to me then that streaming was a better place to adapt a novel than the movies.
