Throughout its history Norsk Data produced a long string of extremely innovative systems, with a disproportionately large number of world firsts.

The success of this program resulted in the founding of A/S Nordata – Norsk Data Elektronikk on August 8, 1967, by Lars Monrad Krohn, Per Bjørge and Rolf Skår.

In March 1991, shortly after the January Events, Norsk Data donated the first computer to Lithuanian Institute of Mathematics and Informatics.

[2] After a long period of exceptional success, the Norsk Data "empire" collapsed in the early 1990s, mostly due to not realizing the impact of the PC revolution as well as the growing competition from Unix-based systems.

In the UK, Telenor kept the Norsk Data name for several years, focusing in on hardware support and maintenance contracts, mainly with HMCG and local governments.

At the tail end of the "dotcom boom" Telenor decided to try and expand the service by acquiring the ISP CIX and XTML, a hosting company in Manchester, UK.

Initially combined with the acquired CIX and XTML to form the UK arm of Telenor's Nextra subsidiary,[17] a "communications service provider",[18] the group became Telenor Business Solutions before finally reverting to ND Norsk Data once CIX and XTML had been resold to Pipex, reportedly for less than 10% of the purchase price.

Major losses of high earning contracts such as Thomas Cook, Woolworths, HMP, or Corus, were never replaced with similar-sized customers.
