In 1992, Arion developed and released its first title, MasterCook PC for Windows. Arion's first title was soon followed by the release of MasterCook II in 1993 and MasterCook Mac in 1994. The success of the MasterCook series has established Arion as the market share leader in the cooking software category.
Sierra On-Line acquired Arion Software on September 12 1995 to add it to its Home Productivity line and establish a leading position in cooking software.
At the time of the acquisition, Arion, located in Austin, Texas, employed 12 people primarily in research and development. David Macdonald, president and co-founder of Arion, continued as producer of the MasterCook series.
