Retail media ad spending is booming in Latin America. Brazil and Mexico are leading the charge, with Mercado Libre outpacing in-market rivals. Here are the latest trends you need to know.

TikTok is laying off hundreds of UK staff as it shifts moderation to AI, with more than 85% of takedowns now automated. The cuts, part of a global restructuring, come as the UK’s Online Safety Act pressures platforms to strengthen oversight. Industry peers are also pivoting—Meta and X have scaled back fact-checking while Reddit, Pinterest, and Snapchat adopt varying models of control. Yet user sentiment runs counter: Most want more human oversight, not less, with strong demand for fact-checkers, privacy, and quality control. The divergence raises brand-safety questions as advertisers weigh cost efficiencies against consumer trust.

Consumers in Japan have been slow to embrace digital technology, but they are gradually warming to it. Recent data shows consumers are changing their online shopping and media consumption behavior.

The news: Instagram is testing a feature that lets users select their favorite movies, books, TV shows, games, and music to encourage intentional sharing and discovery. The offering, called Picks, then surfaces overlapping interests between friends to drive engagement. It’s still an internal prototype and isn’t being tested externally yet. Our take: Effectiveness will depend on user adoption, stickiness, and whether shared Picks sparks meaningful interaction or is perceived as just another data-harvesting ploy. If Picks launches, brands should be ready to experiment with interest-based messaging but prepare to navigate privacy sensitivities.

Some high-engagement platforms are still undermonetized—creating opportunities for advertisers to connect with audiences in less-saturated environments.

Elon Musk plans to sell paid placements within Grok’s AI-generated answers, marking his first major advertiser pitch since Linda Yaccarino’s departure. Grok, X’s in-house AI assistant built by xAI, will integrate ads directly into responses, offering brands high-intent, context-driven targeting. The move comes as X’s global ad revenues, projected at $2.26 billion in 2025, remain roughly half of pre-Musk levels. Musk says Grok will eventually automate the full ad-buying process, from creative grading to personalization, aiming to improve efficiency and performance. With user growth declining in every major region, the strategy hinges on whether brands trust Musk’s AI-led vision enough to re-engage.

The news: Instagram added a host of new features for connecting with friends. The offerings could expand brands’ peer-to-peer visibility and location-based content and boost their chances of going viral. Our take: Brands should lean into organic discovery by creating engaging, visual-driven content that encourages reposts and peer engagement. Prioritize geo-aware promotions to tap into Instagram’s shift toward real-time social discovery and exploration.

The news: Direct messages (DMs) are becoming a key channel to reach consumers as follower growth, once the gold standard for social media success, declines. The average number of shares for brands on TikTok increased 60% quarter over quarter in Q1, per Dash Social’s 2025 Social Media Trends report, showing a pivot toward private content distribution. At the same time, average monthly follower growth for brands on TikTok dropped 27% YoY. Our take: The rise of DMs as a preferred engagement channel signals a deeper shift in social media strategy—from public broadcasting to private conversation—that requires brands to prioritize intimacy to maintain trust and drive meaningful outcomes.

After advertisers spent Q1 2025 reacting to the threat of tariffs, they shifted their focus back to the business of figuring out how social platforms’ automated offerings complement more established methods of investment.

On today’s podcast episode, we discuss why Ms. Yaccarino left X, the expectations for its advertising business in the short and long term, and how realistic its chances are of becoming an “everything app”. Join our conversation with Senior Director of Podcasts and host, Marcus Johnson, Vice President and Principal Analyst, Jasmine Enberg, and Analyst, Marisa Jones.

The news: More than half (51%) of customer service journeys start on search engines and third-party platforms like Google, YouTube, Reddit, and ChatGPT—rather than company websites—prompting businesses to meet customers where they are, per a recent Gartner survey. Our take: Brands need to research and identify the platforms their customers rely on and establish fast, responsive service on those channels. The goal isn’t to pull users back to official websites—it’s to meet them where they already are, with the answers they need, when they need them. Using generative engine optimization (GEO) best practices to boost customer service answers in genAI outputs could help younger consumers get digestible, fast answers in their preferred channel.

The news: Meta is axing political ads in the EU as of October, citing an uncertain regulatory environment with “unworkable requirements.” The company stated in a blog post that the pullback will include ads related to political, electoral, or social issues, and specifically pointed to conflicts with the EU’s Transparency and Targeting of Political Advertising (TTPA) regulation. Our take: Meta's decision signals how fast platforms can change ad policies and how little time marketers have to react. If labeling systems or ad review processes change for the EU—or broadly apply to topics adjacent to social issues—advertisers may need to recalibrate campaigns to avoid triggering enforcement.

The news: TikTok renewed its Lionel Messi-focused live broadcast deal with Major League Soccer (MLS) after a successful 2024 livestream, per a blog post. TikTok will partner with Apple TV to broadcast four select matches in the current MLS season, with a dedicated camera angle focused on Messi during each match. Our take: TikTok and Apple TV’s newest move is another bid to capitalize on a well-known athlete in a profitable genre, where advertising opportunities are plentiful and success is essentially guaranteed. Sports are one of the most reliable ad environments, offering scale, loyalty, and global reach.

The news: Forecasters are mixed on the future of Elon Musk-owned platform X after CEO Linda Yaccarino, whose experience as an advertising executive at NBCUniversal helped X reclaim some ad revenues, stepped down. But things aren’t all gloom and doom: We forecast that X’s ad revenues will increase by 25% YoY in 2025. Our take: While X’s ad revenues will likely grow in the short term, the shift toward AI could alleviate long-term struggles resulting from a turbulent few years for the platform—and even if some advertisers shift away, many will feel pressured to stay or face consequences.

The news: Reddit’s ad business is on a path of steady growth, with ad revenues expected to reach $1.8 billion this year and grow 29% to reach $2.5 billion in 2026, per a new WARC forecast. Brand participation on Reddit shows promising results: One organic brand post per week increases positive mentions by 3.5%. Our take: Though Reddit’s massive growth is partially attributed to its smaller reach, its ability to reach users that aren’t frequenting more popular platforms warrants investment, and a diversified approach combining Reddit’s unique community-driven base with larger platforms’ massive reach is key.

The news: Meta is experimenting with letting users sign up for Threads through Facebook, potentially attracting older users and further separating Threads’ identity from Instagram. Our take: Combining data from Facebook and Threads will give advertisers deeper insights and opportunities to optimize campaigns. Marketers can use this to tailor platform-specific campaigns or create unified cross-platform content to better resonate across demographics.

The news: Fox News is seeing a rise in ad revenues as advertisers look to curry favor with the Trump administration, per a Financial Times report. Advertisers are hoping to reach “an audience of one,” per Fox’s head of ad sales, after it was revealed that President Trump is a regular viewer of the channel. Our take: Ad spending is becoming increasingly political, influenced by who holds power, what media they consume, and how brands position themselves in a partisan media environment. Brands are increasingly expected to take a stance—even if it means aligning themselves with controversy.

Social search is gaining ground. Roughly two-thirds of US consumers search on at least one social platform in ways that can influence every part of the consumer journey.

Social network user growth will be slow on a worldwide level, but 2025’s meager 2.9% increase will still equate to more than 115 million new users. Facebook remains in the lead in most countries and regions, even though its share of internet users is declining.

The news: Linda Yaccarino, CEO of Elon Musk’s X, left the company Wednesday as the social platform faced a major AI controversy—raising questions about the platform’s future and how advertisers will navigate the shift. Yaccarino, who became CEO of X in 2023, announced her decision to leave on Wednesday. Our take: X’s future is increasingly rocky. Yaccarino’s departure reaffirms many advertisers’ fears that the platform is far from stable, and the Grok mishap indicates that it isn’t yet brand safe—meaning major advertisers could retreat once again.
