Everyone in comedy is now either an internet star or an aspiring one.

More so than any other artists, comics adjusted quickly to the new normal, with theaters reinventing themselves as online portals, clubs producing virtual stand-up sets and just about everyone performing on Instagram Live. Jim Gaffigan put his family dinners on YouTube, and Mike Birbiglia live-streamed the development of new jokes with Maria Bamford and John Mulaney. In one of the best pivots, Sam Morril and Taylor Tomlinson, who both recently released stand-up specials, started shooting quick funny videos chronicling a new couple cooped up together in quarantine, and it has grown into a very funny series.

But the comedians doing the most assured work online didn’t need to adjust because they were already there, particularly those in the growing genre of “front-facing camera comedy”: short character sketches played directly to the camera. Owing a debt to the hectic editing of Tim and Eric and the influence of the defunct six-second-or-less platform Vine, these videos have gone viral for years, but with comedians and audiences stuck at home, they have replaced the special as the dominant comedy form of the Covid-19 crisis. In the constantly shifting ecosystem of young performers on Twitter and Instagram, the most vital voice to emerge during this anxious, isolating moment is that of Meg Stalter.

Stalter, 29, has become essential escapist entertainment, an oasis of invigorating silliness in feeds dominated by wearying tragedy. Part of the reason is her staggering productivity. In the last two weeks alone, she started a new podcast, “Confronting Demons,” and performed nearly nightly hours on IG Live, including comic versions of a cooking show, a magic show, a motivational seminar and a master class on the art of seduction. She has also produced more than a dozen flamboyant new characters, from Cameile Orgasm, the self-described richest person in Beverly Hills, to your aunt who just realized she should be in quarantine — along with a bunch of random experiments like recreating a segment from “Sex and the City” and narrating a scene from a Marilyn Monroe movie.

While live in-person comedy has vanished, the Meg Stalter Industrial Complex has filled the vacuum. And though producing such a titanic volume of material from her Brooklyn apartment will inevitably produce uneven results, there is an aesthetic through-line to her comedy, such a signature style that you see online comments refer to people as a Meg Stalter character. So who exactly is that?
