Next week, Comedy Central will host a five-day comedy festival that includes a lineup of legends like Mel Brooks and Carl Reiner alongside popular young comics like Amy Schumer and the director Paul Feig. But there will be no smoky comedy clubs. No lone microphones and stools positioned on stage. No two-drink minimum. The festival will take place almost entirely on Twitter, with comedians posting video snippets of routines and round tables and posting jokes using the hashtag #ComedyFest. The partnership between Comedy Central, a cable cannel owned by Viacom, and Twitter represents the evolving relationship between television and social media. Twitter is often incorporated into programming with viewers using the site as a second screen while watching live television. But slowly, Twitter is becoming an outlet on which to watch video.
