3 April 1971 marks the first time that the Eurovision Song Contest was hosted in Dublin, following Dana's win the previous year.
The Eurovision production was one of the first home produced colour television programmes broadcast by RTÉ.
The Eurovision Song Contest was introduced by Bernadette Ní Ghallchóir from Dublin's Gaiety Theatre.
RTÉ made significant investment in the technology required for colour television throughout the late 1960s and early 1970s. While the first colour transmission was broadcast in 1968, it took a further five years before colour television transmissions became a more regular event. The introduction of colour technology came in stages for RTÉ beginning with sports and other events being taken from the Eurovision network. Investment in colourisation playback equipment allowed for colour transmission of home produced films and video productions. Finally, the studios and Outside Broadcasting Units were converted to full colour.
