Some former and still active employees of Telekom Austria AG (formerly the Post and Telegraph Administration) in Upper Austria joined forces in 2003 to document the development of telecommunications in Austria. Some of these employees were already involved in the preparation of the special exhibition "100 Years of Telephony in Upper Austria" at the Upper Austrian Provincial Museum (Francisco Carolinum) in Linz in 1985/1986. The association "Nachrichtentechnik einst und jetzt" was founded to preserve telecommunications equipment and record historical events.

A telecommunications museum with an extensive collection of telecommunications equipment was set up in the telecommunications building. The museum contains a broad cross-section of equipment that was in operation in Austria after 1945 in the telecommunications networks of the Austrian Postal and Telegraph Administration.

The association's website provides a brief overview of the collection. In addition to the museum, an extensive archive on the history of telecommunications in Austria has been created. The archive is divided into several chronological and thematic blocks and can also be viewed via the "History" link on the website.
