There's a fascinating report about how Dr. Horst Voelz (the most popular computer scientist in Eastern Germany) for the first time in 1987 (edit: 1986) sent BASIC programs "illegally" (meaning without notifying government officials) in a live broadcast from his living room on the GDR "national school radio", which quickly became the most popular radio show in Eastern Germany (the all-in-all 60 radio shows received 50,000 letters which was unheard of), all despite attempts from the Ministry of Education to shut it down.

Here's the PDF of the report written by Dr.Voelz himself:
