With the introduction of giant slalom at the world championships in 1950, the combined event disappeared from the Olympics for four decades, until re-introduced in 1988. From 1948 through 1980, the Winter Olympics also served as the world championships, with two sets of medals awarded. The world champion in the combined was determined "on paper" by the results of the three races of downhill, giant slalom, and slalom. The top three finishers in the combined event were awarded world championship medals by the FIS, but not Olympic medals from the IOC. This three-race paper method was used from 1954 through 1980; no FIS medals were awarded for the combined in 1950 or 1952. A separate downhill and slalom for the combined event was added to the world championships in 1982, and the Olympics in 1988.
