TikTok: What It Is, How It Works, and Why It's Popular

Why It Matters

The forced divestiture and EU investigations could reshape TikTok’s ownership, disrupt advertising spend, and set precedents for data‑privacy enforcement across the tech industry.

Key Takeaways

• TikTok has over 100 million U.S. users, leading Gen Z engagement.
• US law forces ByteDance to divest TikTok U.S. operations by 2025.
• Brands like Chipotle and e.l.f. achieve billions of views via TikTok campaigns.
• EU opens investigations under the Digital Services Act for TikTok’s youth safety.

Pulse Analysis

Since its 2016 launch, TikTok has transformed short‑form video into a global cultural engine. The app’s AI‑driven “For You” feed tailors content in seconds, driving average daily usage that rivals legacy platforms. With more than 5 billion downloads and over 100 million active users in the United States alone, the service commands the attention of Gen Z and Millennials, making it a prime venue for infotainment, product discovery, and influencer‑led commerce. Brands now allocate sizable portions of digital ad budgets to TikTok, betting on viral formats rather than traditional spot ads.

That commercial allure collides with mounting political scrutiny. In April 2024, Congress passed a law requiring ByteDance to sell or spin off TikTok’s U.S. operations by 2025, a deadline repeatedly pushed back by litigation and diplomatic negotiations. The European Commission has also launched two Digital Services Act probes into data protection, advertising transparency, and algorithmic harms to minors. These regulatory pressures threaten advertising continuity, could force a restructuring of the platform’s ownership, and raise compliance costs for marketers who must navigate divergent privacy regimes across markets.

Looking ahead, TikTok’s trajectory hinges on how quickly it can satisfy regulators while preserving the algorithmic magic that fuels engagement. A successful divestiture—potentially involving U.S. partners like Oracle or Walmart—could create a semi‑independent entity that retains its ad infrastructure, reassuring advertisers and investors. Conversely, a ban would open a vacuum for rivals such as Instagram Reels or YouTube Shorts to capture displaced spend. For brands, the prudent strategy is to diversify short‑form content across platforms, while monitoring legislative developments that could reshape the digital marketing landscape.
