Performing is just showing up at comedy shows and doing your bit. That alone would not have made him successful.
He aggressively promoted and marketed himself!
Biggest example: Going on Letterman and other corporate talk shows / interviews (he went on Letterman 12 times to promote himself, not making much money, purely for driving awareness - classic pr marketing technique that he used repeatedly)
He also went far beyond live acts when he started monetizing his recorded acts that were playing/distributing through corporate partners. Those recordings and specials were heavily marketed and he benefited from it because it created scale.
