YouTube Kids has struggled with disturbing videos, like beloved Disney characters in violent or sexual situations, sneaking past its automated filters.Now the app is adding new settings to give parents more control over what videos their kids can see.The company announced Wednesday an option to filter videos by "approved content only," so parents can whitelist channels and subjects.The effort comes four months after reports called attention to troves of videos with inappropriate themes on the video-sharing site's kid-friendly platform. Content for YouTube Kids is selected from the main YouTube app and screened using machine learning algorithms. But some videos, such as cartoons disguised as age appropriate, slip through the cracks.Once the new setting is turned on, users can pick collections from trusted creators such as PBS and Kidz Bop, or themed collections curated by YouTube Kids itself.YouTube is launching another tool later this year that will let parents choose every video or channel their kid can see in the app."While no system is perfect, we continue to fine-tune, rigorously test and improve our filters for this more open version of our app. And, as always, we encourage parents to block and flag videos for review that they don't think should be in the YouTube Kids app," the company said in a blog post announcing the new features.It's the kind of control parents have been asking for from the popular app, but it also puts the onus on them to filter content. It's a side effect of the way YouTube Kids finds its videos.When a video for children is uploaded to the main YouTube platform, it is not automatically added to the YouTube Kids library. The videos are reviewed by machine learning algorithms to determine whether or not they are appropriate for the app.The automated process -- one YouTube calls very thorough -- can take days. A human doesn't check the videos before they're added, but parents can flag videos they find alarming later and a content reviewer will check it out.However, it's unlikely parents are constantly watching YouTube Kids videos along with their children. It's possible this safety guard isn't sufficient for catching every odd video your kid might see.The flag-the-video-later system has created some problems for the service. Some YouTube creators have uploaded concerning videos marked as kids content that slips past the screening process. These videos have included Spiderman urinating on Frozen's Elsa, Peppa Pig drinking bleach, and Micky Mouse getting run over by a car.The company continues to change its rules to crack down on the issue, but creators are constantly looking for ways to trick the system.YouTube Kids still has its main library available by default for now, and the company says it is working on more controls for parents. 2837

— like Big Brother is very much watching. And such systems do dance a fine line between informative and intrusive. But they also could help mitigate the spread of a virus, and that could make the difference between having Michigan Stadium empty on a fall Saturday or having 100,000 fans rooting on the Wolverines again.Not everything will be as overt as barren concourses and empty seats, either. Most of the changes that colleges and teams are implementing will go unnoticed by those who settle in for the kickoff or first pitch.Premier League club Tottenham recently opened its new London stadium after spending millions to create more than 1,600 WiFi access points and 700 Bluetooth beacons, ensuring fans are able to utilize crowd-density apps and other technology. Many facilities are upgrading heating, cooling and ventilation systems to scrub air as it circulates through their buildings, while others are toying with the use of QR codes to monitor the health of their patrons.“We’re extrapolating off these trends that have already existed, and I think we’re going to kick-start into 2025 even though it’s only 2020,” said Jason Jennings, director of strategy and digital integration for the sports and entertainment group at Mortenson, which is wrapping construction on the Raiders’ new .4 billion stadium in Las Vegas. “The technology is going to be deployed much faster because of the value it has for the fan experience and public health.”Even the way facilities are cleaned will change. No longer will hosing down seats and sweeping up trash left by fans be enough. Venue giant ASM Global recently announced a new hygiene protocol for its 325 facilities worldwide, noting the importance of hewing to international health recommendations from the likes of the Centers for Disease Control and the World Health Organization.Few professional teams have been willing to divulge their reopening strategies, whether that be potential seating layouts or infrastructure upgrades. The rapidly changing social and political environment coupled with the unpredictable nature of the virus have made planning difficult. But the Miami Dolphins and Hard Rock Stadium recently committed to being the first public facility to receive a STAR rating from the Global Biorisk Advisory Council, which involves completing a rigorous program to help provide what Dolphins chief executive Tom Garfinkel “the safest environment possible.”Of course, even that might not be enough. While much remains unknown about the novel coronavirus, one fact that is painfully clear is how easily it spreads. No league or team wants their games to become 2630
