originally aired from 1957–1959, with a top prize of 10,000 Danish crowns. It was revived in 1984, then again in 1990 and again in 1999. The latest revival in 2013 was aimed at kids and also included kids as participants. United Kingdom There were three derived versions in the UK: earlier, The 64,000 Question, Double Your Money (see above) and later, The $64,000 Question. Italy The Italian version of this quiz was Lascia o raddoppia? (1955–1959). The prize money doubled from 2,560,000 lire to 5,120,000 lire. Mexico The Mexican version, El Gran Premio de los 64,000 pesos lasted from 1956 to 1994 with some interruptions, changes of name to compensate peso devaluation, and changes of TV network.
