TikTok is a short-form mobile video platform that allows users to create, discover, and share vertical videos. The app uses an algorithmic feed to surface content personalized to each user, while advertisers can run in-feed ads, branded hashtags, and sponsored challenges, with a Business Center to plan and measure campaigns. The platform differs from competitors through a large global creator community, integrated marketing tools, and rapid trend cycles that drive high engagement. Its goal is to inspire creativity and bring joy by helping people express themselves and giving brands a direct way to reach a broad audience.

Anyone looking for some swanky office space in music city? TikTok guts its entire Nashville office after just two years, lays off 250 employees.

Anyone looking for some swanky office space in music city? TikTok guts its entire Nashville office after just two years, lays off 250 employees. Anyone looking for some swanky office space in music city? TikTok guts its entire Nashville office after just two years, lays off 250 employees ashley king august 6, 2026. After announcing a massive expansion in the heart of Nashville, TikTok shutters its office in Music City, laying off 250 people to "streamline" its operations. TikTok's U.S. joint venture has laid off 250 employees in Nashville as the office closes its doors on October 5. Notably, that includes those in charge of content moderation, as those jobs continue feeling pressure from artificial intelligence. "We have decided to close our Nashville office to streamline our operations and better align our teams for long-term growth," said a statement from the company. "We remain fully committed to providing secure, safe, and positive experiences for the 200 million Americans that create, discover, and connect with what they love on TikTok." TikTok did not provide a detailed reason for the layoffs, but employees received emails on Wednesday morning notifying them of the move. Several employees who wished to remain anonymous told The New York Times that they had been logged out of their company devices and told they would receive severance pay. Located in the Moore Building, TikTok's Nashville office occupied nearly 145,000 square feet of space. The company signed the lease in 2024, and the building was sold in July for just under $147 million. Prior to opening its Music Row office, the company had a presence in Nashville for several years, initially occupying several floors at the WeWork building downtown. TikTok opened several major offices across the United States in 2024, including those in Silicon Valley, Seattle, Texas, New York, and Nashville. The Nashville lease marked the city's largest office transaction of the year and nearly tripled the company's office space there. Early this year, ByteDance, TikTok's Chinese parent company, spun off its North American operation into a U.S.-based joint venture. The deal was the conclusion to a lengthy effort to comply with a 2024 federal law that sought to separate TikTok's U.S. operations from ByteDance to address national security concerns. The agreement sees non-Chinese investors own around 80% of the American venture, while ByteDance maintains just under 20%. The U.S. version licenses the platform's lucrative recommendation algorithm from ByteDance.

Insider Paper

TikTok withheld algorithm safety update from 15 million US users during engagement test, report says.

TikTok withheld algorithm safety update from 15 million US users during engagement test, report says. August 6, 2026 1:31 pm A confidential internal review reportedly found that one teenager was placed in a control group where protections against repetitive harmful content were intentionally inactive. TikTok withheld an algorithm safety update from millions of people in the United States while it studied how the change would affect user engagement, according to a confidential company document reviewed by Bloomberg. The experiment reportedly left about 10% of TikTok's US users - roughly 15 million people at the time - on an older version of the recommendation system. The remaining 90% received an updated algorithm designed to prevent users from becoming trapped in repetitive streams of potentially harmful content. TikTok had publicly announced in December 2021 that it was developing ways to interrupt clusters of videos involving subjects such as sadness, loneliness, extreme dieting and breakups. The company said that individual videos might not violate its rules but could create a negative experience when repeatedly recommended together. However, the newly reported document indicates that the safeguard was not immediately activated for everyone. Safety feature became part of an engagement experiment. TikTok reportedly used an A/B test, sometimes described internally as a backtest, to compare users receiving the new safety system with those remaining on the previous algorithm. Such experiments are commonly used by technology companies to measure how product changes affect user behaviour. In this case, however, the feature being tested was intended to reduce repetitive exposure to sensitive and potentially dangerous material. According to the document, TikTok wanted to determine how the update affected daily active users and other engagement measurements. The test reportedly continued for between six months and a year, significantly longer than the short experiments commonly associated with minor product changes. Among the users assigned to the control group was Chase Nasca, a 16-year-old from New York who died by suicide in February 2022. A 14-page internal review prepared by TikTok's safety and algorithm teams in March 2023 found that Nasca's account had entered a recommendation loop dominated by videos involving depression, hopelessness, loneliness, self-harm and suicide. The review stated that TikTok's strategies for preventing filter bubbles did not apply to his account "by design" because he had been included in the control group. Thousands of videos examined. TikTok's internal teams reportedly examined 7,563 videos delivered to Nasca during the final two weeks of his life. Approximately 73% contained recurring themes involving emotional distress, relationship problems, mental-health struggles or suicide awareness but did not violate TikTok's rules. Nearly 10% were found to breach company policies prohibiting content that promotes or normalises suicide and self-harm. The findings do not, on their own, establish that TikTok or its recommendation system directly caused Nasca's death. They do, however, raise serious questions about the risks of excluding users - particularly minors - from safety updates for the purpose of measuring engagement. Nasca's parents later brought a wrongful-death case against TikTok. The lawsuit was dismissed after the company argued that Section 230 of the US Communications Decency Act protected it from liability for third-party content recommended through its platform. An appeal remains pending, according to the reporting. Internal review recommended major changes. The confidential review reportedly recommended reducing future control groups from 10% of users to less than 1%. It also proposed limiting such experiments to seven days rather than allowing the same users to remain without an update for months. Even a 1% control group would leave at least 1.8 million US users without a particular safety feature during testing, the document reportedly acknowledged. TikTok described the 2022 experiment as a routine test intended to determine whether the safety changes were functioning as expected. The company also said it has since refined the way it conducts similar tests, although it did not publicly provide detailed information about those changes. Questions over TikTok's statements to Congress. The timing of the internal review has also renewed questions about what TikTok disclosed to US lawmakers. TikTok CEO Shou Zi Chew appeared before the House Energy and Commerce Committee on March 23, 2023, approximately two weeks after the company examined Nasca's account. During the hearing, Chew described the safety and well-being of teenagers as a core priority for the platform. In written answers submitted to Congress on May 4, TikTok said it did not believe use of the platform had caused users to die by suicide. When lawmakers asked the company to identify cases in which algorithmic A/B testing had harmed users, TikTok responded that its community standards applied to all content shown during such tests. The answers did not mention the control-group experiment or the findings concerning Nasca's account, according to Bloomberg's reporting. In a statement addressing the confidential document, TikTok said it remained deeply committed to protecting users, particularly teenagers. The company said it continues to invest in content-detection technology, enforcement teams and other trust-and-safety operations. The disclosure adds to wider scrutiny of how social-media platforms test changes to recommendation systems and whether users are adequately informed when safety measures are being evaluated against growth and engagement targets. It also presents technology companies with a difficult question: whether safety systems should ever be treated like ordinary product features when withholding them could expose unsuspecting users to foreseeable risks.

eBay continues to bet on live shopping after record quarter.

eBay continues to bet on live shopping after record quarter. eBay touted an increase in eBay Live's gross merchandise volume as it plans to expand it to more international markets in the coming weeks and months. As eBay tries to keep up with competitors like Whatnot and TikTok Shop, the online marketplace is making a bigger push into live shopping after seeing record results. During its second-quarter earnings call on Wednesday, the company noted that eBay Live's gross merchandise volume (GMV) jumped about eight times year-over-year across seven markets, along with increases in viewers, watch time, and items sold. It plans to expand eBay Live to more international markets in the coming weeks and months. "These results reinforce our confidence that Live can deepen engagement, broaden discovery, and increase velocity across the broader eBay marketplace," CEO Jamie Iannone told investors. However, it's important to note that eBay didn't share the exact GMV number, making it difficult to assess how significant the growth is. That said, eBay clearly sees Live as a key growth area, and the feedback from sellers and buyers looks promising. eBay reports that over 90% of sellers who stream regularly have seen their GMV grow, and those who use Live sell about three times more than those who don't. Buyers are also spending more. First-time shoppers in the collectibles category are dropping around 70% more than their non-Live shopping counterparts. eBay launched Live as invite-only in the U.S. in 2022, then expanded internationally, starting with a beta in the U.K. in 2024, and it has since rolled it out in countries like Germany, Australia, France, Italy, and Canada. Last month, the company moved past its invite-only model and now offers self-service onboarding for eligible sellers in over 300 categories, which include everything from electronics to fashion and collectibles. The company also pointed to recent product improvements, including discovery features across its homepage and mobile app to make live events easier to find. Iannone added that eBay also simplified event creation, inventory preparation, and live item management for sellers, while improving "bidding responsiveness" to create smoother, faster livestreams. The growth comes as live shopping in the U.S. moves beyond a niche trend, with more companies beginning to treat it more seriously rather than a side experiment. Even resale giant StockX recently introduced live shopping capabilities. Whatnot continues to find success, with a valuation of more than $11 billion. Additionally, TikTok Shop is reportedly testing a paid membership that offers free shipping and exclusive discounts.
