Colbert's other gaming guest is PewDiePie, who's making an appearance on the same show as Snapchat founder Evan Spiegel, as it happens. The YouTube celeb has 40 million followers and over 10 billion page views -- and is rumored to be getting his own TV show. He'll also give a "demonstration," according to the CBS Late Show run-down, though there's no mention of which game he'll play (and how he'll avoid cursing). The two appearances mark the first gaming appearances on Late Show, though Colbert's rivals all do segments around it, including Conan O'Brien's "Clueless Gamer," and Jimmy Fallon's "Xbox with My Mom." Colbert has also done a "Gamergate" segment on Colbert Report, but it'll be interesting to see how he handles it outside his former conservative buffoon persona.
