Mari Matsunaga, Takeshi Natsuno, Keiichi Enoki, 1999

This mobile Internet service is especially popular in Japan. i-mode was launched in 1999 by Japan’s leader in wireless technology: NTT DOCOMO. The content planning and service design was led by Mari Matsunaga, while Takeshi Natsuno was responsible for the business development. Keiichi Enoki oversaw the technical and overall development (stay with us and read on). Just like WAP, it uses a packet switching system to transfer data from one terminal to another. i-mode is very common in Japan, but in all the places around the world where the technology was introduced, it was phased out again due to a lack of interest.
