The phenomenal success of Harry Potter earned author JK Rowling a staggering £77 per minute of last year. Nice work if you can get it! JK Rowling is the only non-American to appear in Forbes Magazine’s Top Ten Celebrity Pay Packets for last year. She comes in ninth with estimated earnings of £41million. Wow! Not bad when you think that the idea for Harry Potter was something that just popped into her head on a train journey!
