Network Information Services, owned 25% by McDonnell-Douglas Corp, 30% by Marubeni Corp, trebled its paid-up capital to $19.6m on May 30, to enable it to expand its international and Japanese domestic value-added network services: the company plans to use the capital to expand its operations to Europe and US, having been the first to start value-added services between Japan and the US when the international networks market was liberalised in December last year; the number of its users increased in leaps and bounds to 100 companies by February this year, and again to 200 users now; as part of its expansion, Network Information Services will greatly increase the number of international leased lines it leases from Kokusai Denshin Denwa, taking two more 14.4Kbps lines, which it plans to use for international value added networking and remote computing services.
