Technological advances
Colour TV
Colour television test broadcasts were started in March 1967, with the first large-scale colour broadcasting occurring for the 1968 Winter Olympics in Grenoble, France.[2] DR officially ended "test" transmissions of colour television on April 1, 1970. However, it wasn't until 1978 that their last black-and-white television program (TV Avisen) switched to colour.[2]
Teletext
On 16 May 1983 at 14:00 CEST, DR launched its first teletext information service, which is still available on all DR channels.[3]
Widescreen TV
In 2004 DR announced plans for a complete switch from a 4:3 screen ratio to 16:9 widescreen broadcasts. The switch occurred in 2006 when DR moved its production facilities from TV-Byen to DR Byen in Copenhagen. The last of DR1's productions to switch to widescreen was the daily news programme (TV Avisen) in November 2006.[4]
Digital TV
At midnight on November 1, 2009, the analogue broadcasts shut down nationwide and DR switched to digital broadcasting.[5][6]
High-definition
In January 2012, DR1 switched from 576iSD to 720pHD broadcasting.[7]
HbbTV
In April 2014, DR launched its HbbTV service on DR1, enabling on-demand streaming of DR content directly on an internet-connected television.[8]
