PC and Software

Founding of the SoftBank Group and rise of the PC

September 1981

Nihon SoftBank created to distribute packaged software

While studying in the U.S., Masayoshi Son came across a striking picture of a microchip on a science magazine, which convinced him that the age of personal computers was coming.

He named his company Nihon SoftBank (current SoftBank Group Corp.) ―a software bank that would serve as the infrastructure of the new information society to be built in Japan.

May 1982

Entered publishing business, launching Oh! PC and Oh! MZ

As PCs became more popular in Japan, Nihon SoftBank launched Oh! PC and Oh! MZ in May 1982.

The unique style of SoftBank’s magazines gained much public attention.

Following the launch of OTC trading in July 1994, SoftBank Corp. (current SoftBank Group Corp.) acquired a computer trade show operator and a publisher in the U.S.
Masayoshi Son describes the acquisition as a way to “get a map and a compass” for a voyage into the center of information technology. The acquisition of Ziff-Davis Publishing Co., a publishing division of Ziff Communications Company, helped discover embryonic Yahoo! Inc. in the U.S.
