FIS Freestyle Ski and Snowboarding World Championships 2015  The 2015 FIS Freestyle Ski and Snowboarding World Championships were held in Kreischberg, Austria from January 15–25, 2015. In 2014, the FIS (International Ski Federation) decided to merge the FIS Freestyle World Ski Championships with the FIS Snowboarding World Championships starting with these championships. The Austrian municipality of Kreischberg was awarded the event in 2010. Qualification for the women's aerials event began a day before the opening ceremony. Freestyle skiers competed in six disciplines: moguls, dual moguls, ski cross, slopestyle, halfpipe and aerials. Snowboarders competed in six disciplines: halfpipe, slopestyle, parallel slalom, parallel giant slalom, big air and snowboard cross. A total of 40 countries entered athletes. For the first time ever the championships were available for live viewing on YouTube for free of charge, in countries where broadcasting agreements were not in place.
