Mark Zuckerberg announced today that Facebook will cancel any large physical events with more than 50 people through June 2021. Some will be held as virtual events, but Facebook has not yet shared specifics. Zuckerberg also said the company will extend its policy of no business travel through at least June of this year, and it will require “the vast majority” of its employees to work from home through at least the end of May.

Facebook already canceled this year’s F8 developers conference, which was scheduled for May 5th and 6th. Today’s announcement means that F8 won’t take place (at least in person) next year either. It looks like Oculus Connect, which typically happens in September, will be canceled, and GDC 2020, which Facebook said it would not attend, has been canceled as well.

Of course, Facebook is hardly the first to make such a move. MWC, which takes place in Barcelona at the end of February, was cancelled after multiple high-profile companies pulled out. Similarly, many companies are deciding to pass up on exhibiting at the GDC conference in San Francisco next month — Sony, Facebook and Microsoft have all decided not to participate.

At this point, it’s fair to wonder if some of the spring’s other marquee tech events, like Microsoft Build and Google I/O, will be happening. These cancellations we’ve seen thus far this year highlight how the global health community doesn’t quite have a handle on the coronavirus spread, something that’s probably making participants and organizers alike reluctant to take part in events like F8.

“If you use the Instagram camera, you’ll see all these AR effects, and they’re all built with Spark,” said Matt Roberts, a Spark product manager. “Now we’re allowing anybody, not just people who work for Instagram, to build their own effects for their own cameras.”

Facebook launched its Camera Effects platform in 2017, which was then renamed to Spark AR last year. Pretty much every AR experience you encounter across Facebook’s family of products was made by Spark AR. According to CEO Mark Zuckerberg, more than one billion people have used AR experiences powered by the company’s Spark AR platform so far. For over a year now, developers have been experimenting and uploading their own effects on Facebook’s camera app, while the Instagram program was in a closed beta. But now it’s open, allowing even more developers to make their own Instagram filters.

What this means for you and me, is even more AR effects on Instagram than ever before. You might see them from brands you follow; maybe Ray-Ban will release an AR effect that’ll let you try on sunglasses, or maybe Marvel will publish different superhero AR masks for you to try on. During the aforementioned closed Instagram beta, it has already implemented third-party filters from Kylie Jenner, Buzzfeed, Vogue, the NBA and more.

The Spark AR Studio is apparently so easy to use — we’re talking drag-and-drop functionality — that any artist or creator can make their own AR filters and publish them on Instagram with relative ease (Roberts did tell me there’s a team that’ll vet the AR filters to make sure they’re appropriate before publishing). Spark AR Studio is free and runs on both Windows and Mac OS.

After creating their AR effect, creators can then publish it to their Instagram profile, or share it on a story. When followers see the effect, they can select it and use it in their stories. Their followers can then do the same thing, creating a domino effect and potentially sparking a viral phenomenon. Each third-party-created AR effect will say who the creator is on the bottom, so the original account will still get all the credit, and perhaps a few extra followers in the process.

With so many AR effects and filters on Instagram in the pipeline, however, it’s going to be a little difficult to find the one you want. For now, the best way to find the latest and greatest AR effects is by following your favorite creators (You can find some over at Lenslist or follow the Spark Creators account). Eventually though, they’ll be easier to locate. According to Roberts, Instagram is working on discovery solutions and ways to surface the AR effects you might be interested in.

“We’ve had folks who are relatively unknown creatives getting access to thousands of followers,” said Roberts. “We think AR is a new creative medium for all kinds of artists.”

Facebook’s F8 developer conferences tend to be chock-full of news, and that’s truer than ever for 2019. The company’s opening keynote brought major changes to just about every corner of Facebook’s universe, including a site redesign, a super-lightweight Messenger app, Instagram shopping and new features to find friends or hook up with your secret crush. And then there’s the hardware — Oculus finally committed to release dates for the Quest and Rift S, while Portal will be available beyond the US. It’s a lot to handle, but you don’t have to worry about wading through it all. We’ve rounded up the highlights of F8 in a video that will get you up to speed in short order.
