From the dawn of time to about 10 years ago, not much changed in comedy. People stood around being funny, sometimes with friends. Other people laughed, within earshot, on the sofa, or stuck in traffic. Then we saw the potential of the Internet for more than porn. Podcasts became the new radio. YouTube showed up and nobody knew what to do with it—at first. Ditto Twitter. Five years ago Instagram arrived, giving credence to doughnut pics and selfie sticks. Vine’s only been around two years and has already launched careers—even in porn: grunt, moan, sigh, repeat.
