Red Bull has an aggressive international marketing campaign. The numerous sponsored activities range from extreme sports like windsurfing, snowboarding, skateboarding, kayaking, wakeboarding, cliff-diving, surfing, skating, freestyle motocross, rally, Formula 1 racing, and breakdancing to art shows, music, and video games. In keeping with their target market of young males, Red Bull has also enlisted help from celebrities, such as Eminem that would appeal to this group (sponsoring the Red Bull "EmSee Battle Rap championships"). It also hosts events like the "Red Bull Flugtag" (German for "flight day" or "flying day") and other such contests. Red Bull also sponsors association football teams, with clubs in Austria, Germany, the United States and Brazil featuring the Red Bull trademark in their names. By associating the drink's image with these activities, the company seeks to promote a "cool" public image and raise brand power. In addition, the slender container is used to suggest a "sexier" image than some other cola counterparts. Hence, this one energy drink has helped create a market for over 150 related types of merchandise, like Red Rooster and Blue Lightning.
