Twitch continues to lead rivals including, YouTube Live, Facebook Gaming and Microsoft’s Mixer, when it comes to live-streaming video. Despite experiencing its first decline in hours watched in Q2 2019, the Amazon-owned game-streaming site still had its second-biggest quarter to date, with more than 70% of the hours watched during the quarter.

According to a new report from StreamElements, Twitch viewers live-streamed a total of 2.72+ billion hours in Q2 — or 72.2% of all live hours watched — compared with 735.54 million hours on YouTube Live (19.5%), 197.76 million on Facebook Gaming (5.3%) and just 112.29 million hours (3%) on Mixer.

Combined, the total hours watched across all four platforms was 3.77 billion in Q2.

While none of Twitch’s rivals are nearly catching up, YouTube Live did have a good month in May, breaking its own record with 284 million hours watched. Overall, YouTube Live’s hours watched improved in Q2 as a result, while Twitch saw a slight decline.

Facebook Gaming is also gaining steam. It’s now the third-biggest live-streaming platform, having passed Microsoft Mixer.

Despite its traction, Twitch doesn’t have much of a long tail when it comes to stream viewership. That’s a problem it has faced for some time, as newcomers complained they spent years broadcasting to no one in hopes of gaining a fan base, with little success. Twitch has tried to remedy this problem with various educational efforts as well as product features like Raids and Squad Streams, for example.

However, the new report finds that the majority (almost 75%) of Twitch’s viewership still comes from people tuning in to the top 5,000 channels. Out of the 2.7 billion hours watched in Q2, these top 5,000 channels drove 2 billion of those hours watched.

In addition, the average concurrent viewership (viewers watching at the same time) of the top 5,000 channels increased by 12% in Q2 2019, compared with Q1. The top 200 channels have the highest concurrent viewership with 10,590 people watching together, on average.

Also in the quarter, viewership of top titles like Fortnite, League of Legends, Dota 2 and Counter-Strike: Global Offensive declined, while vlogging — aka “Just Chatting” — grew, along with other titles.

Esports, meanwhile, still draws big numbers, but represents only a small slice of the overall pie.

YouTube lands on Fire TV and Amazon Prime Video arrives on Chromecast, Android TV

Posted by | Amazon, Amazon Fire TV, Android, Android TV, Apps, chromecast, Cube, Gadgets, Google, Media, Multimedia, prime, prime video, smart tv, streaming, streaming video, TC, technology, telecommunications, YouTube | No Comments

It’s nice when people can come together and work through their differences to make it easier to watch stuff. That’s exactly what happened today, when the long-standing detente between Google and Amazon over streaming video services came to an end, with YouTube arriving on Fire TV and Prime Video making its way to Chromecast and Android TV.

Amazon’s second-generation Fire TV Stick, their Fire TV Stick 4K, the Fire TV Cube, Fire TV Stick Basic Edition and Fire TV Edition smart TVs made by partner OEMs will all get support for the official YouTube app globally starting today, and Amazon intends to extend support to even more of its hardware in the future. YouTube TV and YouTube Kids will also come to Amazon Fire TV devices later this year.

On the Google side, both its own Chromecast devices, as well as partner TVs and hardware that support Chromecast built-in, or that run Android TV, will gain support broadly for Prime Video. Plus, any Chromecast Ultra owners will also get access to Prime Video’s 4,000-title library normally reserved for Prime members, at no additional cost, as part of the new tie-up between the two companies.

Prime has been available on some Android TV devices to date, but it’s expanding to a much broader selection of those smart TVs and streaming boxes from today.

This has been a long time coming — several years in fact, with the most recent spat between the two coming as a result of Amazon’s implementation of YouTube on the Echo Show. Then, in May, the companies announced they’d reached an agreement to put the feud behind them in the interest of consumers, which is what resulted in this cross-platform launch today.

Let the streams flow!

Tesla’s in-car touchscreens are getting YouTube support

Posted by | Android, automotive, cars, e3 2019, electric vehicles, Elon Musk, in-car navigation, Louisiana, Media, streaming video, TC, Tesla, tesla model 3, Tesla Model S, YouTube | No Comments

Tesla has consistently been adding software to its in-car touchscreen infotainment displays — including sometimes things that probably leave a lot of people scratching their heads. During a special Q&A today at annual gaming event E3 in LA, Tesla CEO Elon Musk revealed that Tesla’s in-car display will support YouTube someday soon.

This isn’t the first time the Tesla CEO has suggested YouTube might one day have a home in the company’s cars: In response to a fan’s question on Twitter last August he noted that version 10 of the company’s in-car software would provide support for third-party video streaming. The company debuted its Software Version 9.0 last year.

Musk specifically said YouTube would be coming to cars during the E3 event today, at which he revealed that Bethesda’s Fallout 3 would be coming to the infotainment displays, and unveiled a demo video of Android game Beach Buggy Racer running on a display in a Tesla Model 3.

On a recent podcast, the Tesla CEO also said the company would consider opening the platform more broadly to third-party developers for both apps and games. The company has done a lot on its own to add software “Easter Eggs” to the dash display, but turning it into a true platform is a much more ambitious vision.

On its face, adding to a car attention-heavy apps like streaming video services definitely seems counterintuitive, but to be fair to Tesla, a large number of drivers today use their phones for in-car navigation and those can also all technically display YouTube at any time. It does seem like a case of Musk’s mind racing ahead to a day when his cars are fully autonomous, something he recently reiterated he expects to happen within the next couple of years.

Apple TV+ makes Facebook Watch look like a joke

Posted by | Amazon Prime Video, apple tv, Apps, Entertainment, Facebook Watch, Media, Mobile, Netflix, Social, streaming video, TC | No Comments

Apple flexed its wallet today in a way Facebook has been scared to do. Tech giants make money by the billions, not the millions, which should give them an easy way to break into premium video distribution: buy some must-see content. That’s the strategy I’ve been advocating for Facebook but that Apple actually took to heart. Tim Cook wrote lines of zeros on some checks, and suddenly Steven Spielberg, JJ Abrams, Reese Witherspoon, Jennifer Aniston, and Oprah became the well-known faces of Apple TV+.

Facebook Watch has…MTV’s The Real World? The other Olsen sister? Re-runs of Buffy The Vampire Slayer? Actually, Facebook Watch is dominated by the kind of low-quality viral video memes the social network announced it would kick out of its News Feed for wasting people’s time.

And so while Apple TV+ at least has a solid base camp from which to make the uphill climb to compete with Netflix, Facebook Watch feels like it’s tripping over its own feet.

Today, Apple gave a preview of its new video subscription service that will launch in fall offering unlimited access to old favorites and new exclusives for a monthly fee. Yet even without any screenshots or pricing info, Apple still got people excited by dangling its big-name content.

Spielberg is making short films out of the Amazing Stories anthology that inspired him as a child. Abrams is spinning a tale of a musician’s rise called Little Voice Witherspoon and Aniston star in The Morning Show about anchoring a news program. Oprah is bringing documentaries about workplace harassment and mental health. Apple even has the Seasame Street gang teaching kids how to code.

This tentpole tactic will see Apple try to draw users into a free trial of Apple TV+ with this must-see content and then convince them to stay. And a compelling, exclusive reason to watch is exactly what’s been missing from…Facebook Watch. Instead, it chose to fund a wide array of often unscripted reality and documentary shorts that never felt special or any better than what else was openly available on the Internet, let alone what you could get from a subscription. It now claims to have 75 million people Watching at least one minute per day, but it’s failed to spawn a zeitgeist moment. Even as Facebook has scrambled to add syndicated TV cult favorites like Firefly or soccer matches to free, ad-supported video service, it’s failed to sign on anything truly newsworthy.

That’s just not going to fly anymore. Tech has evolved past the days when media products could win just based on their design, theoretical virality, or the massive audiences they’re cross-promoted to. We’re anything but starved for things to watch or listen to. And if you want us to frequent one more app or sign up for one more subscription, you’ll need A-List talent that makes us take notice. Netflix has Stranger Things. HBO has Game Of Thrones. Amazon has the Marvelous Mrs. Maisel. Disney+ has…Marvel, Star Wars, and the princesses. And now Apple has the world’s top directors and actresses.

Video has become a battle of the rich. Apple didn’t pull any punches. Facebook will need to buy some new fighters if Watch is ever going to deserve a place in the ring.

Media fragmentation is annoying consumers

Deloitte’s Technology, Media and Telecommunications division published its 13th-annual Digital Media Trends survey, focused on identifying changes in the ways US consumers engage with various types of media.

Led by an independent research firm, the survey had roughly 2,000 consumer respondents across demographics – with the report categorizing respondents based on age (Gen-Z: ages 14-21, Millenials: 22-35, Gen-X: 36-52, Boomers: 53-71, and Matures: 72+).

While already accompanied by a succinct 13-page executive summary, the report can largely be summarized in just a couple of sentences: more people are using streaming or alternative media services than ever before, largely due to more user freedom and customization, though the growing quantity and fragmentation of platforms are becoming more frustrating for users to manage.

The survey results directionally echo already well-discussed dynamics, which we’ve previously dug into such as here, here and here. Instead, the most poignant aspects of the report were not the answers or conclusions themselves, but the immense level of support many of them received.

Jeffrey Katzenberg’s streaming service Quibi is doing a show about Snapchat’s founding

Posted by | Evan Spiegel, Jeffrey Katzenberg, Media, meg whitman, Mobile, Quibi, snap inc, Snapchat, streaming video, TC | No Comments

Jeffrey Katzenberg and Meg Whitman today announced a slate of new series and projects heading to their forthcoming video streaming service, Quibi. The list includes an origin story to complement Telemundo’s hit show “El Señor de los Cielos;” a music competition show produced by Justin Bieber manager and entertainment exec Scooter Braun; a show from Jennifer Lopez’s company about the power of giving and paying it forward; as well something called “Frat Boy Genius,” which will focus on the rise of Snapchat — and specifically its creator, Evan Spiegel.

“It is the story of how he built and created Snapchat, which is one of the great social platforms of our time,” touted Katzenberg. “And we want to tell a story that is as compelling and interesting about the creation of Snapchat and Evan’s story as “[The] Social Network” was for Facebook,” he added.

The project will be based on the screenplay by the same name, which had written Spiegel as a hard-partying Stanford student, according to Vulture’s review of the much-hyped script.

“He should be flattered,” remarked Katzenberg, of Quibi’s plans for the Spiegel-focused project.

And now to the featured scripts! First up: @Elissits‘ FRAT BOY GENIUS, illustrated by @boxbrown. pic.twitter.com/GW8KQclrrB

— The Black List (@theblcklst) December 17, 2018

Katzenberg and Quibi CEO Meg Whitman were at SXSW to speak about the upcoming streaming video service, which plans to offer short-form video designed for mobile. On Quibi, consumers watch “quality” video cut into smaller pieces, including both scripted and unscripted original content, exclusives from Quibi’s partners and other daily news and sports programming.

Already, some of Quibi’s content plans have been announced.

For example, Deadline reported last fall that filmmakers Sam Raimi, Guillermo del Toro and Antoine Fuqua and producer Jason Blum will all create series for the service. And a pitch deck had touted other examples of Quibi’s programming — like a show called “Inspired By” with Justin Timberlake and “Under the Gun” with Kobe Bryant. Plus, Katzenberg himself had revealed in a LinkedIn post that Quibi was working on a basketball-related series with Steph Curry’s production company.

However, the story about Snapchat’s founding highlights how Quibi could benefit from its combination of tech and entertainment industry roots, in terms of deciding what to greenlight.

Whitman, a former HP Enterprise president and CEO, also pointed to another example: her penchant for using data to make decisions.

“I am deeply analytical and Jeffrey will argue in stories and allegories,” Whitman said. “And I will say: ‘Jeffrey, do you have any data to suggest that what you have just said is true?’ And he’ll say, ‘no I don’t have any data — but it’s true,’ ” she explained.

“Then I will come with data, facts, total available market size, market segmentation, market research, and he will say, ‘you know, not everything yields to analysis.’ And I’ll say ‘no, not everything does, but most things do,’ ” she said.

For the most part, today’s onstage discussion was a pitch for why Quibi will work and why it needs to exist — with Katzenberg touting its promise as an app that will benefit from 5G mobile networks as well as the cord-cutting behavior among younger millennials, who are no longer interested in traditional pay TV.

Both execs also stressed that Quibi was not a Netflix or YouTube competitor — despite angling for the same share of consumers’ mobile minutes and a set amount of downtime not spent on social media and mobile gaming, for example. They instead believe Quibi will be additive, and other services — like Netflix and Disney+ — can still win, even as Quibi wins.

Katzenberg said that Quibi aims to grab 20 minutes of the 70 minutes per day people spend watching short-form video, but doesn’t believe it will necessarily come at the expense of YouTube or others.

“Six years ago it was six minutes. A year and a half ago, it was 40 minutes. And today it’s 70 minutes,” he said, illustrating mobile video’s rise. “People love being able to watch great short-form content on the go.”

“What we know is that our users are watching a lot of video on mobile. They’re excited about the opportunity to see something differentiated. But honestly, we’re using a lot of judgment, and we’ll know whether it works when it launches,” Whitman added. 

Quibi will publish more than 100 pieces of content every week, meaning it’s going to be making 5,300-5,400 pieces of content per year, Katzenberg said. He also mentioned a few others examples of programming, including a daily round-up of the best of late night TV, and spoke more vaguely of the potential for a show that delivered music news, the way that MTV’s Kurt Loder once did.

The streaming service is launching in April 2020, Katzenberg also confirmed today, putting a more definitive time stamp on the launch time frame beyond “early 2020” or “spring.”

Netflix launches ‘smart downloads’ feature on iOS to automate offline viewing

Posted by | Apps, cord cutting, Downloads, iOS apps, Media, Mobile, Netflix, offline, streaming, streaming service, streaming video, tv, Video | No Comments

Netflix today is launching a new feature on iOS devices that will help make it easier to watch its shows when you’re offline. The “smart downloads” feature, as it’s called, will automatically delete a downloaded episode after you’ve finished watching, then download the next one — but only when you’re connected to Wi-Fi.

The idea is that users will no longer have to go through the tedious work of managing their downloads — deleting those they’ve watched or downloading new titles, for example. Instead, the app can manage the downloads for you, so people can spend more time watching Netflix shows.

Smart downloads make sense for those who plan for intermittent connectivity — like commuters who take underground trains, for instance, or those who travel through dead spots where wireless coverage drops. It also makes sense for those on limited data plans, who are careful about not using streaming video apps unless they’re on Wi-Fi.

Offline features like this are key to attracting and retaining users in emerging markets where connectivity concerns are the norm. That’s likely why Netflix prioritized Android over iOS, for the initial launch of smart downloads.

The feature had first arrived on Android last summer. It’s now offered across platforms, including iOS and in the Windows 10 Netflix app, the company says.

Offline access is only one area where Netflix is focusing on the needs of those in developing markets. The company late last year also began testing a more affordable, mobile-only subscription.

Non-U.S. users accounted for 7.31 million of the 8.8 million new subscribers Netflix added in the last quarter, as the U.S. market has become more saturated.

To use smart downloads on iOS, you can toggle the option in the Netflix app settings. It then turns itself on when you’re connected to Wi-Fi, to ensure your data plan won’t be used and your device storage won’t fill up as you watch offline. The feature will alert you when the episode in question has been downloaded.

“The faster our members can get to the next episode of their favorite stories, the better. Now, fans on the Netflix iOS app can get in on the fun and convenience of Smart Downloads, spending less time managing their downloads and more time watching,” said a Netflix spokesperson in a statement about the launch. “The feature is one more way we’re making it easier for Netflix fans to take the stories they love wherever they go,” they added.

Facebook Watch is finally growing as payouts get spread thin

Posted by | Apps, Entertainment, Facebook, Facebook Watch, Facebook Watch Party, Fidji Simo, Media, Mobile, Social, streaming video, TC | No Comments

Both Facebook Watch and Instagram’s IGTV have yet to become superstar video platforms, leaving Facebook at risk as more people seek streaming entertainment instead of status updates. So today Facebook is trying to build some buzz for Watch with new stats and rollouts. The free video hub that combines original content, sports and cult favorite TV shows like Firefly now has 400 million users watching at least one minute per month. That’s not a ton of engagement amongst a wide audience. But on the brighter side, there are 75 million users watching at least one minute per day with a much more promising average of 20 minutes per day.

Though that’s just 5 percent of Facebook’s 1.5 billion daily users, it indicates that if Facebook can get people hooked on its ad-supported shows, it could squeeze serious viewing time out of them. Just four months ago, Facebook was saying that only 50 million people spent at least 1 minute per month on Watch, so it’s making strong progress.

Watch is now available worldwide on desktop and Facebook Lite, as well as the main Facebook app. And it’s rolling out ad breaks to 40 countries after an initial launch in five in August. It’s also renewing four shows for a second season: Huda BossFive PointsSacred Lies & Sorry For Your Loss.

But The Information reports that news media executives feel that while some shows are getting satisfactory viewership, ad revenue has been underwhelming. Six months ago, Facebook commissioned news programs from outlets like CNN and BuzzFeed. Facebook reportedly now plans to pay news video content producers less per show as it seeks to spread the same $90 million budget across more programs, potentially with a greater focus on international markets. That cut-back could make producing some shows tough, but at least the execs believe Facebook understands it must prioritize monetization for its content partners.

To the end, Facebook plans to offer more options for advertisers like more targeting capabilities, and expanding its In-Stream Reserve premium ad inventory inside the top-quality Watch shows. For individual video creators, Ad Breaks will become more widely available, including within game streams from esports stars. Facebook is also planning to expand its Brand Collabs Manager to additional countries so creators can get hooked up with sponsorship deals, and let more creators sign up fans for Patreon-style subscription payments.

The viewing stats have likely been bolstered by the addition of all episodes of Joss Whedon’s old TV shows Buffy The Vampire Slayer, Angel and Firefly that users can binge watch for hours on end; indeed, 12 million Watch Party group video sessions have been launched to date, helping shows go viral. Facebook is now testing live picture-in-picture commentating that could let actors host viewing parties that feel like you’re sitting in the living room beside them. Facebook’s VP of video Fidji Simo writes that “With Facebook Watch, we set out to demonstrate what it looks like to build deep bonds through watching online video, instead of just having a passive viewing experience.”

Simo also notes that “People can find videos on Facebook in a number of different places — Watch, News Feed, Search, Pages and more — and all of these can feel different. We want to make the experience of watching video feel immersive no matter where you discovered it. As part of this effort, we’ll be testing a few things in the coming months, like creating a darker background whenever you immerse yourself into a video on mobile.”

Facebook has yet to concentrate its funding on a blockbuster tentpole video series — its Game of Thrones or House of Cards. The closest thing it has is the Elizabeth Olsen show Sorry For Your Loss, though viewership has been somewhat weak. Next year Facebook Watch will debut a revived and social media-infused web version of MTV’s Real World. But tapping its deep pockets to pay for one must-see original scripted series could help wedge Watch into people’s lives.

YouTube Kids adds a whitelisting parental control feature, plus a new experience for tweens

Posted by | children, families, kids, Media, Mobile, parental controls, parents, streaming video, TC, Video, YouTube, youtube kids | No Comments

YouTube Kids’ latest update is giving parents more control over what their kids watch. Following a change earlier this year that allowed parents to limit viewing options to human-reviewed channels, YouTube today is adding another feature that will give parents the ability to explicitly whitelist every channel or video they want to be available to their children through the app.

Additionally, YouTube Kids is launching an updated experience to serve the needs of a slightly older demographic: tween viewers ages 8 through 12. This mode adds new content, like popular music and gaming videos.

The company had promised in April these changes were in the works, but didn’t note when they’d be going live.

With the manual whitelisting feature, parents can visit the app’s Settings, go to their child’s profile, and toggle on an “Approved Content Only” option. They can then handpick the videos they want their kids to have access to watch through the YouTube Kids app.

Parents can opt to add any video, channel, or collection of channels they like by tapping the “+” button, or they can search for a specific creator or video through this interface.

Once this mode is enabled, kids will no longer be able to search for content on their own.

While this is a lot of manual labor on parents’ part, it does serve the needs of those with very young children who aren’t comfortable with YouTube Kids’ newer “human-reviewed channels” filtering option, as mistakes could still slip through.

A “human-reviewed” channel means that a YouTube moderator has watched several videos on the channel, to determine if the content is generally appropriate and kid-friendly, but it doesn’t mean every single video that is later added to the channel will be human-reviewed.

Instead, future uploads to the channel will only go through YouTube’s algorithmic layers of security, the company has said.

YouTube Kids expands to tweens

The other new feature now arriving will update YouTube Kids for an older audience who’s beginning to outgrow the preschool-ish look-and-feel of the app, and the way it sometimes pushes content that’s “for babies,” as my 8-year old would put it.

Instead, parents will be able to turn on the “Older” content level setting that opens up YouTube Kids to include less restricted content for kids ages 8 to 12.

According to the company, this includes music and gaming videos – which is basically something like 90% of kids’ YouTube watching at this age. (Not an official stat. Just what it feels like over here.)

The “Younger” option will continue to feature things like sing-alongs and other age-appropriate educational videos, but YouTube Kids’ “Older” mode will let kids watch different kinds of videos, like music videos, gaming video, shows, nature and wildlife videos, and more.

YouTube stresses to parents that its ability to filter content isn’t perfect – inappropriate content could still slip through. It needs parents to participate by blocking and flagging videos, as that comes up.

It’s best if kids continue to watch YouTube while in parents’ presence, of course, and without headphones, or on the big screen in the living room where you can moderate kids’ viewing yourself.

But there are times when you need to use YouTube as the babysitter or a distraction so you can get things done. The new whitelisting option could help parents feel more comfortable letting their kids loose on the app.

Meanwhile, older kids will appreciate the expanded freedom. (And you won’t be constantly begged for your own phone where “regular YouTube” is installed, as a result.)

YouTube says the parental controls are rolling today globally on Android and coming soon to iOS. The “Older” option is rolling out now in the U.S. and will expand globally in the future.

Correction: An earlier version of this post referenced the lack of a blacklisting feature. This was incorrect – blacklisting by channel or video is possible. This section was removed shortly after publishing. Apologies for the error.

Technique to beam HD video with 99 percent less power could sharpen the eyes of smart homes

Posted by | backscatter, Gadgets, hardware, Mobile, science, streaming video, TC, wireless | No Comments

Everyone seems to be insisting on installing cameras all over their homes these days, which seems incongruous with the ongoing privacy crisis — but that’s a post for another time. Today, we’re talking about enabling those cameras to send high-definition video signals wirelessly without killing their little batteries. A new technique makes beaming video out more than 99 percent more efficient, possibly making batteries unnecessary altogether.

Cameras found in smart homes or wearables need to transmit HD video, but it takes a lot of power to process that video and then transmit the encoded data over Wi-Fi. Small devices leave little room for batteries, and they’ll have to be recharged frequently if they’re constantly streaming. Who’s got time for that?

The idea behind this new system, created by a University of Washington team led by prolific researcher Shyam Gollakota, isn’t fundamentally different from some others that are out there right now. Devices with low data rates, like a digital thermometer or motion sensor, can something called backscatter to send a low-power signal consisting of a couple of bytes.

Backscatter is a way of sending a signal that requires very little power, because what’s actually transmitting the power is not the device that’s transmitting the data. A signal is sent out from one source, say a router or phone, and another antenna essentially reflects that signal, but modifies it. By having it blink on and off you could indicate 1s and 0s, for instance.

UW’s system attaches the camera’s output directly to the output of the antenna, so the brightness of a pixel directly correlates to the length of the signal reflected. A short pulse means a dark pixel, a longer one is lighter, and the longest length indicates white.

Some clever manipulation of the video data by the team reduced the number of pulses necessary to send a full video frame, from sharing some data between pixels to using a “zigzag” scan (left to right, then right to left) pattern. To get color, each pixel needs to have its color channels sent in succession, but this too can be optimized.

Assembly and rendering of the video is accomplished on the receiving end, for example on a phone or monitor, where power is more plentiful.

In the end, a full-color HD signal at 60FPS can be sent with less than a watt of power, and a more modest but still very useful signal — say, 720p at 10FPS — can be sent for under 80 microwatts. That’s a huge reduction in power draw, mainly achieved by eliminating the entire analog to digital converter and on-chip compression. At those levels, you can essentially pull all the power you need straight out of the air.

They put together a demonstration device with off-the-shelf components, though without custom chips it won’t reach those

A frame sent during one of the tests. This transmission was going at about 10FPS.

microwatt power levels; still, the technique works as described. The prototype helped them determine what type of sensor and chip package would be necessary in a dedicated device.

Of course, it would be a bad idea to just blast video frames into the ether without any compression; luckily, the way the data is coded and transmitted can easily be modified to be meaningless to an observer. Essentially you’d just add an interfering signal known to both devices before transmission, and the receiver can subtract it.

Video is the first application the team thought of, but there’s no reason their technique for efficient, quick backscatter transmission couldn’t be used for non-video data.

The tech is already licensed to Jeeva Wireless, a startup founded by UW researchers (including Gollakota) a while back that’s already working on commercializing another low-power wireless device. You can read the details about the new system in their paper, presented last week at the Symposium on Networked Systems Design and Implementation.
