The obvious area is in films -- much of the Pixar film work is ray traced as are most of the final high-quality visual effects done in Hollywood. This is a common assumption, but it turns out to be less true than you'd expect. People associate raytracing with ultra-realistic graphics, so they assume that realistic graphics must be raytraced. But the reality is that graphics creators go out of their way to avoid raytracing because it is slow and harder to tweak for artistic effect. Pixar didn't add raytracing to their main renderer until "Cars". (http://graphics.pixar.com/library/indexAuthorBatali.html http://graphics.pixar.com/library/indexAuthorBatali.html)
