Casady & Greene, founded in 1984 by Robin Casady, was a software publisher of shareware products, primarily for the Macintosh. C&G published fonts in the earlier days of desktop publishing; founder Casady partnered with Michael Greene, founder of Greene Inc who developed QuickDex. An expansion into games came in 1987, when they published Crystal Quest by Patrick Buckland. This game marked their only foray into the Amiga market.
Other software to follow were the security suite AME, crash recovery utility Crash Barrier, InfoGenie, iData, Let's Keep It Simple Spreadsheet (Let's KISS), Spreadsheet 2000, InstaFiles! and various games: Sky Shadow, Mission Starlight, Glider, Aqua Blooper Piper, Pararena, Mission Thunderbolt, Spaceway 2000, Silicon Casino, Glider PRO, AmoebArena, Step On It!, Zone Warrior I and II, and Crystal Crazy.
C&G was the initial distributor of SoundJam MP, a program which was the basis for Apple Computer's iTunes. They also distributed Conflict Catcher and Spell Catcher, popular tools for the Classic Mac OS. On July 3, 2003 C&G closed their doors officially due to ongoing financial problems, the result of continuing difficulty in selling their products due to the difficulty in transition from the Mac OS "Classic" environment to the fundamentally different Unix-based one offered by Mac OS X.
