The Eurovision Song Contest 1957 was the second Eurovision Song Contest. Like the first contest, this one was still mainly a radio program, but there was a noticeable increase in the number of people with televisions. For some time, a rumour has existed that the German entry "Das Lied vom Großen Glück" by Walter Andreas Schwarz came second at the 1956 contest and that that is why Germany hosted ESC 1957. In fact, the rule stating that the winning nation hosted the next year's Eurovision had not yet been conceived, and it was planned at the time that each participating country would take it in turns to host the event. However, as more countries wished to participate, this became impractical. In this year's contest the Italian entry lasted for 5:09 minutes, whilst the UK's entry lasted for only 1:52 minutes. It was because of songs like the former that a rule was eventually introduced restricting each song to a maximum of 3 minutes; this rule still applies today. Birthe Wilke and Gustav Winckler at the end of their song exchanged the longest kiss that has ever occurred in the contest - although, of course, only people with televisions could actually see it. This was due to a member of the production staff forgetting to give a pre-arranged sign that the kiss should end. It was the first time the Netherlands won the contest. Source: Wikipedia
