In 1992, Jon Stephenson von Tetzchner and Geir Ivarsøy were members of a group of research to Televerket, the Norwegian public company of telecommunications (from now on named Telenor). The group took share with the development of ODA, a system based on standards for storage and the document retrieval, image and other digital contents. System ODA was not never used with large scales in spite of its effectiveness and was abandoned. The group of research also created first Norwegian waiter Internet and their first personal pages in 1993.
The members of the group thought however that the navigator Mosaic had a structure “punt” to be effective too much in navigation on the Web. On the basis of these observation, the group was interested in the principle of developing a new navigator of documents on the basis of nothing. Inspired by project ODA, they transfer the potential of the development of a navigator more adapted to the multiple facets of the structure of the Web. Their company Televerket mother gave them green light and at the end of 1993, the first prototype was construct and functional.
However, Televerket was vis-a-vis a dilemma: a total deregulation of the Norwegian market of telecommunications was planned for the year 1998, which meant that they were to prepare with competition. They were not sure that the navigator would correspond to their core activity. In 1994, Televerket became a public limit company where the State was majority shareholder, and von Tetzchner and Ivarsøy was authorized to continue the development by themselves in the buildings of Televerket.
End 1995, Televerket changed name for Telenor, and the Opera Software company was then created in the same buildings as before. Their product was initially known under the name of MultiTorg Opera and was quickly recognized by the community of the Net surfers for his interface multidocuments (MDI) and its “ hotlist ” (bars side) which facilitated the consultation of several pages at the same time.
