A product entry strategy-the timing of entry, the magnitude of investm
ent at entry, and the area of competitive emphasis at entry-affects lo
ng-term performance in the marketplace. The authors develop the Entry
Strategy Performance Model (ESPM) and propose an encompassing framewor
k for product entry strategy research. They empirically test a researc
h model derived from the ESPM through an examination and replication i
n the microcomputer software market. The authors' significant findings
are that initial competitive positioning and media coverage (an atypi
cal market characteristic) drive long-term performance.
