History
The DTM architecture was conceived in 1985 and developed at the
Royal Institute of Technology (KTH) in
Sweden.
It was published in February 1996.
The research team was split into two spin-off companies, reflecting two different approaches to use the technology. One of these companies remains active in the field and delivers commercial products based on the DTM technology. Its name is Net Insight.
