Aktenzeichen XY was initially produced in the ZDF studios in Wiesbaden, before moving to the FSM studios in Unterföhring from 1969. From 15 March 1968, the Austrian public broadcaster ORF became a joint producer of Aktenzeichen XY, with a segment focusing on Austria hosted first by Thaddäus "Teddy" Podgorski (de) from 1968 until 1971, then by Peter Nidetzky (de) from 1971 until 2002; which from 24 January 1969 was also joined by Schweizer Fernsehen (SF), with a segment focused on Switzerland hosted firstly by Werner Vetterli from 1969 until 1976, then by Konrad Toenz (de) from 1976 until 1998, and finally Stephan Schifferer from 1998 until 2002.
