The records of the video periodicals made by Black Box were deposited in 2011 at the Blinken–OSA Archives, Budapest. The Archives received a unique and invaluable video and textual collection, including the complete 150-hour long video documentation of the 1989 Opposition and National Roundtable Negotiations, the copies of some 90 short documentaries, all the political programs of Hungarian Television in 1989, together with unedited footage produced by Black Box in 1988–1989, its documentary films, and a number of paper-based documents.
The transfer of the collection was followed by a press conference at OSA, with the participation of István Jávor and Márta Elbert, founding members of Black Box Foundation. As Elbert stated, the decision to hand over the collection to OSA was also motivated by the chance to reach a wider public, since the Archives promised that all records of the Opposition and National Roundtable Talks would be available online too. Further plans for the future of the collection were also presented to the public. Accordingly, the documentary films by Black Box would be used in the weekly television broadcast of the Archives, and the complete collection would be digitized, including some further records to be conveyed at a later date. According to the contract made between the Foundation and the Archives, the legal status of the archival transfer is “deposition,” and the collection would be used for the purposes of research and education only.
