Informational television programs and the orientation of "Deutschlandfunk" (Germany's national public radio station, associated with, but not a member of the ARD) programs towards the GDR were of importance to the eventual collapse of the GDR. Established in 1974, the ARD bureau in East Berlin made ARD television the most important source of information for GDR citizens, eighty percent of whom could watch what they referred to as "Westfernsehen". Notwithstanding obstruction on the part of GDR authorities and the repeated expulsion of their correspondents, the ARD-Tagesschau and Deutschlandfunk transmitted reports about the Leipzig Monday Demonstrations (which started on 4 September 1989) as early as September 1989.
