Bulgaria's first entry was Bon-Bon with "Bonbolandiya", which finished 7th at the 2007 contest in Rotterdam. Their second entry was Krestiana Kresteva with "Edna mechta", which finished 15th and last at the 2008 contest.
The Bulgarian broadcaster BNT withdrew from the 2009 contest, and Bulgaria did not compete in the contest in Kiev or at the 2010 edition in Minsk. Bulgaria returned for the 2011 contest in Yerevan, then they took a break from the 2012 and the 2013 contests.
Their success helped reinvigorate public interest in the contest. According to Google Trends, Junior Eurovision was the eighth fastest trending event in Bulgaria for 2014, ahead of the Australian Open 2014 and New Year's 2014.
On 26 January 2015, it was announced that Bulgaria would host the 2015 edition at the Arena Armeec in Sofia on 21 November. The 2015 junior contest has been credited by some for providing BNT with the financial support they needed to return to the adult Eurovision in 2016, for their first Eurovision since 2013 - perhaps not coincidentally, their entrant in Stockholm was the Junior Eurovision's 2015 host, Poli Genova.
