Fandango is most commonly known as a retailer of movie tickets. They are owned by NBC and Universal. Fandango charges service fees for purchasing tickets through the service and its main appeal has been for purchasing tickets to blockbuster movie openings that may be quickly sold out or require standing in a long line. The tickets can be purchased via their online site or they may be bought over the phone.
Another meaning for fandango, as well as the original one, is that of a Spanish dance. The dance was likely brought to Spain by Moors in the 18th century. It is a couples dance performed in triple meter and accompanied by acoustic guitar music and hand claps or castanets.
