RTL plus was already known through the
radio station. Even before the broadcast began, the pressure on politicians to introduce private television in Germany was growing in Saarland, which could be reached from the broadcasting systems in Luxembourg. Private television began operations in the Federal Republic of Germany on January 1, 1984 with the two-year
Ludwigshafen cable pilot project (Kabelpilotprojekt). It was the birth of PKS (later Sat.1). A day later, RTL plus, which was then broadcasting from Luxembourg and named after the Luxembourg radio and television broadcaster RTL (derived from Radio Télévision Lëtzebuerg, see also
RTL Télé Lëtzebuerg), began its German-language program from 5:27 p.m. The unusual broadcast start took place in a small studio in Bertrange with the following scene: Chief doctor Rainer Holbe delivered a television with the RTL-plus logo in a delivery room with his obstetricians. The broadcast times were Monday to Friday from 5:30 p.m. to 10:30 p.m. and Saturday to Sunday from 5:30 p.m. to midnight. The first RTL broadcast after the starting signal was the news 7 vor 7 with Hans Meiser and Geert Müller-Gerbes. RTL plus was famous in its early years for showing low-budget films and American programmes. In 1988, it was the second most-viewed channel in Germany. After
reunification in 1990, broadcasting was extended to the entire country. RTL moved to
Cologne and received the right to broadcast on free-to-air frequencies. That same year, RTL acquired the first-run rights to the
German Football First Division. Deals with
Cannon and
Universal Studios finally provided more high-profile films for the channel. In 2012, RTL made a deal with
Walt Disney Studios Motion Pictures to air films from its media library until 2016, when it switched to Universal, as Disney Channel was relaunched as a free-to-air channel competing with RTL. In July 2015, the channel introduced the slogan Willkommen zuhause (Welcome home) to complement Mein RTL, and launched its biggest advertising campaign in 20 years. This tagline (as Willkommen zu Hause, with a space between zu and Hause) was earlier used in the early 2000s. On 1 September 2017, RTL flattened its logo, with brighter shades of the three colours. The slogan continues to be
Willkommen zuhause, through
Mein RTL would be used in rare cases. Another sister channel,
n-tv was rebranded on the same day. As part of a comprehensive restructuring within
Mediengruppe RTL Deutschland, RTL unveiled a new identity, a new, multi-colourful logo and a new graphics package. The rebrand rolled out on 15 September 2021, as well as
RTL Crime,
RTL Living and
RTL Passion. == Station logos ==
