Case study videos. I could watch them all day long. They're my favorite form of media entertainment—apart from sitcoms starring Concord grapes, that is. These days, advertising case studies are so creative and well produced, they're often more enjoyable than the crappy campaigns they show off. And dammit, they deserve an award show of their own.Which brings us to this spoof video from Rethink Communications introducing the Caseys, honoring excellence in advertising award show submissions. "Cannes, One Show, the Clios. These shows celebrate the very best in creativity," the voiceover begins. "But none of them celebrate what we do best as advertising professionals—the case study video."
