Here is a little more info on the beginnings of the SP:

"Originally, the short program for singles had only 6 required elements (three jumps, two spins, and one step sequence). It was competed for the first time at Nebelhorn Trophy in late summer of 1972. A seventh element, the spin combination, was added to the short program the following season. Required deductions for failures on elements were not added until the 1975-1976 season. The eighth element (spiral sequence for ladies or second step sequence for men) was added in the 1988-89 season, when the time limit was set at 2 minutes 40 seconds. The short program was extended by an additional 10 seconds when the ISU Judging System was adopted to allow skaters more time to complete complex spins and step sequences.
It used to be that the required elements in the short program were more constrained than they are now. For example, at the 1988 Winter Olympics, both men and ladies were required to do a double flip as the jump out of steps, and include a double loop in the jump combination. The change to allow men to do a triple as the required axel jump and include a quadruple jump in the short program did not happen until the 1998-99 season."
