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.
The worldwide box office was $1,835,300,000, which made it one of the top grossing movies of all time. Adjusting for inflation, Gone With The Wind (1939) is the top grossing movie of all time. As of Jan. 24, 2010, Avatar has made $551,741,499 in the United States. It has made $1,287,060,822 in foreign markets. Avatar has made $1,838,802,321 worldwide. Titanic has made $1,843,201,268 worldwide.
