From the page: "Before hitting on success, the series creators, Lloyd Ahlquist and Peter Shukoff, each struggled for a decade in live comedy, doing cheap shows in cheap clubs anywhere they could. In 2010, Shukoff branched out into online videos, but few people even noticed his uninspired YouTube sketches and songs.
Finally, after a disappointing improvisational theater session in 2010, the two comics hit on an idea that consumers actually liked: the Epic Rap Battles of History.
Shukoff and Ahlquist made a couple of 2-minute rap-battle videos, and the viewers suddenly flocked to them in the millions. The advertisers followed. And fast as they could, the investors rolled in to support and improve the product with capital goods (like green-screen studios and closets full of wigs.)"
