Information Services International-Dentsu, Ltd. (ISID) was established in 1975 as the first private computer time-sharing service (TSS) provider in Japan, a joint venturebetween Dentsu Inc., the world’s largest independent advertising firm in terms of revenues, and General Electric Company (GE), one of the leading blue-chip companies in the United States. In this era before personal computers or the Internet, the aim of the project was to utilize GE’s massive computer center over international networks to provide Japanese companies with innovative services.

Supported by Japanese leading corporations in the manufacturing and financial industries who aimed for overseas expansions, TSS of ISID acquired the largest market share. The experience we gained by providing numerous leading-edge business applications on the TSS network is the foundation of the services we offer today, including product development solutions for the manufacturing industry and system development for financial, retail and service industries.Today, the business environment is changing, including the utilization of the Internet of Things (IoT) and Big Data, and industry revolution on a global scale.

Under such environment, ISID continues to provide the best solutions with leading-edge technologies and extraordinary business knowledge as well as service capabilities that were all cultivated and accumulated since its appearance as a TSS provider. ISID also plays a role as the IT solutions business of Dentsu Group, and provides the group with the underlying marketing platform. To create new solutions for 2020 and beyond, ISID is also accelerating its service development with cutting-edge technologies such as location-based and sensing.
