#multiple wins

The Netherlands was the first country to win more than once, and is the only country to have already achieved this feat in the 50s

Every country that won the 1969 contest had won at least once already

The only Eastern country with a repeat win is Israel

Spain is the only country to have won back-to-back and never to have won again, and is also the only country with only one repeat win whose two wins were less than 25 years apart

Austria hold the title for longest gap between wins with 48 years

The longest streak of re-wins was 11 years (1990-2000)

The longest streak of first-time winners was 8 years (2001-2008)

The most common number of years between wins is either 1, 2 or 10 years, with five repeated wins taking each number of years to occur.

Excluding Spain, the most concentrated set of wins comes from Ireland, with an average gap of 4 contests per win (helped greatly by their four near-consecutive wins in the 90s)
