The story
The channel was created following the election of Helmut Kohl who announced the creation of the first cable pilot projects, the first of which began on 1 January 1984 in Ludwigshafen. The channel launched on that day as PKS, one day before the launch of competitor RTL. The channel wasn't successful, as only 2,600 households received it (even though it enabled nationwide coverage using a weak satellite), and RTLplus, which initially broadcast from Luxembourg, upon obtaining a VHF frequency (channel 7) unused from West Germany, gained a foothold. Leo Kirch was PKS's largest shareholder, though he had indirect control. Early evening programming included non-commercial and sophisticated current affairs programmes and news magazines, which were seen as boring for the average viewer.
The first face seen on PKS was that of Jürgen Doetz.
