—Past, present - future—

Abstract

NTT's laboratories were established in 1948 as the Electrical Communication Laboratories of the Ministry of Communication, four years later in 1952 became the Electrical Communication Laboratories of the Nippon Telephone and Telegraph Public Corporation. It continues to exist after privatization and reorganization.

In this paper, we summarize the R & D strategy after 1952.

Changes in NTT's R & D strategy were (1) monopoly era (1952–1985), (2) competition era (1985–1999), (3) era of open (1990–2014), (4) B 2 B 2 X era (2014 Year). And we introduce how to proceed R & D in each era, along with examples.
