Apogee Software

Overview

Apogee Software was the company that invented the episodic shareware model, proving that giving away Episode 1 for free would drive sales of Episodes 2 and 3. Founded by Scott Miller in 1987, Apogee published some of the most important PC games of the early 1990s including Commander Keen, Duke Nukem, and—as publisher—Wolfenstein 3D. Their model changed how games were distributed.
