In economics, demand is the desire to own anything, the ability to pay for it, and the willingness to pay. Basically Demand refers to how much (quantity) of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. (see also supply and demand). The term demand signifies the ability or the willingness to buy a particular commodity at a given point of time.

Economists record demand on a demand schedule and plot it on a graph as a demand curve that is usually downward sloping. The downward slope reflects the relationship between price and quantity demanded: as price decreases, quantity demanded increases. In principle, each consumer has a demand curve for any product that he or she would consider buying, and the consumer's demand curve is equal to the marginal utility (benefit) curve. When the demand curves of all consumers are added up, the result is the market demand curve for that product. If there are no externalities, the market demand curve is also equal to the social utility (benefit) curve.

Dr. Henry Walton "Indiana" Jones, Jr. is a fictional character and the protagonist of the Indiana Jones franchise.

Alongside the more widely known films and television programs, the character is also featured in novels, comics, video games, and other media. Jones is also featured in the theme park attraction Indiana Jones Adventure, which exists in similar forms at Disneyland and Tokyo DisneySea.

Jones is most famously played by Harrison Ford and has also been portrayed by River Phoenix (as the young Jones in The Last Crusade), and in the television series The Young Indiana Jones Chronicles by Corey Carrier, Sean Patrick Flanery, and George Hall. Doug Lee has supplied Jones's voice to two LucasArts video games, Indiana Jones and the Fate of Atlantis and Indiana Jones and the Infernal Machine, while David Esch supplied his voice to Indiana Jones and the Emperor's Tomb and John Armstrong in Indiana Jones and the Staff of Kings.
