Propaganda has been through several line-up changes in its recording career:

1984, ZTT (Dr. Mabuse)
Michael Mertens, Suzanne Freytag, Claudia Brücken, Ralf Dörper, Andreas Thein

1985, ZTT (Duel, A Secret Wish, p:Machinery, Wishful Thinking)
Michael Mertens, Suzanne Freytag, Claudia Brücken, Ralf Dörper

Claudia Brücken left Propaganda in 1986 and the remaining members of the group took ZTT to court to release them from their contract. New album demos were recorded in 1987-88. Mertens, Freytag and Dörper were joined by Derek Forbes and Brian McGee along with vocalist Betsi Miller. Although Freytag and Dörper contributed to the new album, they were no longer members by its release.

1990, Virgin (Heaven Give Me Words, 1234, Only One Word, Your Wildlife)
Michael Mertens, Betsi Miller, Derek Forbes, Brian McGee
This line-up fizzled out in 1991.

By 1998 Mertens was working again with Brücken and Freytag, and in 1999 Propaganda's website announced a new album was being recorded. This line-up were set to sign with EastWest, but this was not to be, and the album remains unreleased, although recordings leaked via the internet.

In November 2004, Mertens, Freytag, Brücken and Dörper reunited for a performance of Dr. Mabuse to benefit The Prince's Trust and to celebrate Trevor Horn's 25 years in the music industry.

In 2005, Mertens and Freytag resurrected the name again…
