, with estimated earnings of more than $72 million in the last year alone. Madonna earned much of this income from her H&M clothing line; a deal with NBC to air concert footage; and her Confessions tour—the highest-grossing tour for a female artist to date. She also continued to sing, act and manage a number of business interests, splitting her time between the United Kingdom and the United States. She was the writer and executive producer of I Am Because We Are , a documentary about the lives of Malawi's AIDS orphans, and the art-house film Filth and Wisdom, both with 2008 releases. Her album Hard Candy was released in April of the same year, and her Sticky and Sweet tour became her first major venture with concert promoter Live Nation.
