Joanne "Jo" Rowling, better known as J. K. Rowling, is a British novelist, best known as the author of the Harry Potter fantasy series. The Potter books have gained worldwide attention, won multiple awards, sold more than 400 million copies to become the best-selling book series in history and been the basis for a popular series of films, in which Rowling had overall approval on the scripts as well as maintaining creative control by serving as a producer on the final instalment. Rowling conceived the idea for the series on a train trip from Manchester to London in 1990.
Rowling has led a "rags to riches" life story, in which she progressed from living on social security to multi-millionaire status within five years. As of March 2011, when its latest world billionaires list was published, Forbes estimated Rowling's net worth to be US$1 billion.[9] The 2008 Sunday Times Rich List estimated Rowling's fortune at £560 million ($798 million), ranking her as the twelfth richest woman in the United Kingdom. Forbes ranked Rowling as the forty-eighth most powerful celebrity of 2007, and Time magazine named her as a runner-up for its 2007 Person of the Year, noting the social, moral, and political inspiration she has given her fans. In October 2010, J. K. Rowling was named 'Most Influential Woman in Britain' by leading magazine editors. She has become a notable philanthropist, supporting such charities as Comic Relief, One Parent Families, Multiple Sclerosis Society of Great Britain, and Lumos (formerly the Children's High Level Group).
On February 23, 2012, Little, Brown & Company announced it would publish Rowling's first novel for adults.
