The early 90's saw the transition into programs with the full set of triples plus the early quads as well as the end of figures. A different crop of skaters emerged in the early 90's, and jumps were emphasized over all other aspects of skating.
Also in the 70s and in the 80s jumps were more important than spins, steps and other skating movements. The only difference was that figures were a lot more important than jumps.
