Yet at the Consumer Electronics Show in January 1985, Nishi claimed half a million MSX machines had been sold in Japan and a hundred thousand in Europe
The domestic shipment value of personal computers in fiscal 1988 totaled ¥649 billion (up 23 percent over fiscal 1987); the domestic shipment volume was 1,375,000 (up 14 percent over 1987). The value of domestic shipments has recorded annual growth. Conversely, the volume of domestic shipments of personal computers stabilized at the 1,200,000-nit mark for four years beginning in fiscal 1984. However, this volume began to increase rapidly in fiscal 1988.
The home computer market in Japan consumed 1.1 million machines last year and is growing modestly in 1985, but it remains essentially a game market. (...) The two largest producers of home computers in Japan—NEC Corp., which claims a 40% market share, and Sharp Corp., which claims 20%—do not use the MSX (Microsoft Extended Basic) system that Microsoft Corp. developed and has licensed to 18 other Japanese companies. Total MSX sales last year are estimated at 350,000 units. But NEC's best-selling 8801-MII is used mostly by university students and small businesses for bookkeeping or document filing; MSX users are overwhelmingly 15 years of age or younger—game fanatics.
The volume of domestic shipments of the MSX remained at the 150,000 mark, for a marked decline of 56 percent from 1987.
Traditionally, dominated by Japanese vendors, the market had reached 2.5 million units in 1989, and 3.3 million units in 1991 (Dataquest Inc.)
