Three countries have won twice in a row, Spain (1968 and 1969), Luxembourg (1972 and 1973) and Israel (1978 and 1979). Along with Switzerland's win in the first contest, Serbia is the only other country to win with its debut entry (in 2007), though Serbia had competed prior as part of Yugoslavia and Serbia and Montenegro .

Portugal's Salvador Sobral holds the record of the highest number of points in the contest's history, earning 758 with the song "Amar pelos dois". Norway's Alexander Rybak holds the largest margin of victory in absolute points, a 169 - point cushion over second place in 2009 . Italy's Gigliola Cinquetti holds the record for largest victory by percentage, scoring almost three times as many as second place (49 points compared with 17 by the runner - up) in the 1964 contest . Under the voting system used from 1975 until 2015, the lowest winning score was Norway's Bobbysocks! 123 points earned (of the 216 available from the 18 other countries) when winning Eurovision 1985, while the lowest winning total ever is the 18 points (of the 160 total votes cast by 16 countries) scored by each of the four winning countries in 1969 . </P>
