Red Bull BC One is an annual international b-boy (breakdance) competition organized by the energy drink company Red Bull. It is an individual (or 'one on one') b-boy competition (as opposed to a crew competition). The main event is a knockout tournament featuring sixteen b-boys, chosen for exceptional skills in the dance and good character, competing in one-on-one battles decided by a panel of five judges. 2007 was the only year when winners of worldwide regional knockout tournaments preceding the main event, along with the prior year's top finishers as well as wild card selections, comprised the final group of 16.
The event has been held in a different city and country every year. In 2004 it was held in Biel, Switzerland, 2005 in Berlin, Germany, 2006 in São Paulo, Brazil, 2007 in Johannesburg, South Africa, 2008 in Paris, France, 2009 in New York City, USA and 2010 in Tokyo, Japan.
An official Red Bull BC One DVD was released for the 2004 and 2005 events. The production of the DVDs has been criticized due to musical rights, as the live music played during the competition had to be dubbed over. From 2006 and on, Red Bull stopped releasing DVDs and made the videos available online for free. Alastair Siddon directed a film about the Red Bull BC One 2007. The title of that movie is "Turn it Loose".[dated info] .
