Harry Potter published because of an 8-year-old girl

The first several publishers author J.K. Rowling tried rejected it outright, all for the reason: It was far too long for a children’s book.
Anyway, deciding that she needed an agent, Rowling thumbed through a directory and chose Christopher Little because the name sounded like a character in a children’s book.
She shipped her manuscript off to Little’s office, where it met a familiar fate: An assistant tossed it straight into the rejection pile because Little thought that children’s books didn’t make any money.
Eventually Rowling’s illustrations caught the eye of Little’s assistant while she was sending out the rejections.
Finally, Little shipped it off to Bloomsbury Publishing, where chairman Nigel Newton agreed to look at it as a personal favor.
Newton then did something that apparently never occurred to other children’s book publishers, which was to show it to an actual child.
He offhandedly tossed the manuscript to his 8-year-old daughter, who devoured it in hours and came back to him demanding more.
