I want to know the answer to the following question:
Who named Madonna as the top-earning celebrity of the year?
All the background I'm provided with is that "It was a box office success with a gross of $305.2 million from 88 sold-out shows, and became the highest-grossing tour of 2012 and the tenth highest-grossing tour of all time.". Is that enough to answer the question?
Answer: no
