With a worldwide box-office gross of over $2.7 billion, Avatar is often proclaimed to be the highest-grossing film, but such claims usually refer to theatrical revenues only and do not take into account home video and television income, which can form a significant portion of a film's earnings.
It became the fifth film grossing more than $1 billion worldwide, and the only film of 2009 to do so. In its fourth weekend, Avatar continued to lead the box office domestically, setting a new all-time fourth-weekend record of $50,306,217, and becoming the highest-grossing 2009 release in the United States.
