In 2005, the internal selection of Estonian girl band Vanilla Ninja, performing the song "Cool Vibes", qualified Switzerland to the final where they placed 8th.

SRG SSR idée suisse confirmed their intentions to participate at the 2011 Eurovision Song Contest on 1 September 2010.

Along with their participation confirmation, the broadcaster also announced that the Swiss entry for the 2011 contest would be selected through a national final for the first time since 2004 due to increased popularity for Eurovision in Switzerland after victories for Norway and Germany.
