Stand-up comedians of a certain era knew they had arrived when Johnny Carson invited them to a desk-side seat on “The Tonight Show.” A generation later, the gold standard was getting a solo comedy special on HBO. But in the Internet era, the yardstick for success has been redefined.

A handful of top-tier performers have begun producing stand-up specials on their own, posting them online and selling them directly through their personal Web sites, eliminating the editorial control of broadcasters and the perceived taint of corporate endorsements.

While this straight-to-the-Internet strategy is far from ubiquitous in stand-up, it is already having a profound impact on the comedy landscape, enabling online content providers and individual artists to take more turf from television networks and empowering comedians to be as candid (and as explicit) as they want in their material.

“It’s a very rare thing, where you answer to no one at all as a comedian,” said Aziz Ansari, a stand-up comic and actor who released his first online performance special on Tuesday. “Now you can even put it out the way you want.”
