Upon its introduction, giant slalom briefly displaced the combined event at the world championships; it was absent in 1950 and 1952. The combined returned in 1954 in Åre, Sweden, but as a "paper race," using the results of the three events (downhill, giant slalom, and slalom), a format used through 1980. The combined returned as a stand-alone event at the world championships in 1982 at Schladming, Austria, and at the 1988 Calgary Olympics. It was changed to the super-combined format (one run of slalom on same day as downhill) at the world championships in 2007 and the Olympics in 2010.
