In 1995 a decision was made to (officially) start licensing the Mac OS and Macintosh ROMs to 3rd party manufacturers who started producing Macintosh "clones". This was done in order to achieve deeper market penetration and extra revenue for the company. This decision led to Apple having over a 10% market share until 1997 when Steve Jobs was re-hired as interim CEO to replace Gil Amelio. Jobs promptly found a loophole in the licensing contracts Apple had with the clone manufacturers and terminated the Macintosh OS licensing program, ending the Macintosh clone era. The result of this action was that Macintosh computer market share quickly fell from 10% to around 3%.
