Nippon Telegraph and Telephone Corporation traces its roots back to 1869 when the telegraph was first introduced in Japan. NTT was originally established in 1952 as a government-owned corporation, and it was in 1985 that NTT was privatized. Since then, the company has been diversifying into new markets, forming new subsidiaries and developing leading-edge technologies.
