The way we watch video has fundamentally changed. For years, horizontal widescreen was the standard—cinema, television, YouTube. But the rise of smartphones and apps like TikTok and Instagram Reels has triggered a seismic shift: vertical video is now the default format for billions of users. This transformation goes beyond mere orientation; it's reshaping content production, platform strategies, and even AI development. From Cloudflare's new portrait video support to Google Gemini's AI-powered tools, the vertical video takeover is here—and it's only getting started.
The Evolution of Screen Orientation
As David Pierce noted in The Verge's The Stepback newsletter, social platforms once had distinct identities. YouTube was for clips, Instagram for photos, Twitter for news. But today, nearly every platform is converging on a single format: vertical, full-screen, short-form video. TikTok led the charge, forcing Instagram to pivot to Reels, YouTube to launch Shorts, and even Netflix to experiment with vertical previews. The why is simple: people hold their phones vertically, and watching full-screen feels more natural and immersive.
This shift has created new opportunities and challenges. For brands like KFC Thailand, vertical video is a canvas for viral marketing. According to roastbrief.us, KFC turned a local pain point into a Songkran spectacle with a giant landmark takeover and limited-edition flip-flops—likely leveraging vertical video to drive engagement. While the full details are behind a 403 error, the headline underscores how brands are using vertical formats to capture attention during cultural moments.
Platforms Race to Support Vertical Video
Infrastructure is catching up. Cloudflare recently announced high-definition portrait video support for its Stream service, enabling developers to deliver crisp vertical video at scale. In a blog post, Cloudflare detailed new encoding optimizations that preserve quality while reducing bandwidth, making it easier for creators and enterprises to adopt the format. This is a clear signal that the industry is betting big on vertical as the future of online video.
Meanwhile, contentgrip.com reports that the ongoing TikTok US deal is driving users to alternatives like Skylight and UpScrolled. These platforms are capitalizing on uncertainty around TikTok's fate, offering vertical video experiences with promises of better monetization and creator tools. The deal—which involves potential ownership changes or bans—has users exploring new homes for their short-form content, further fragmenting the landscape but reinforcing the dominance of the vertical format.
AI Takes Over Short-Form Content
Artificial intelligence is supercharging the vertical video revolution. According to quasa.io, Sora 2—a next-generation AI video generator—has even MrBeast sweating. The tool can produce realistic, high-quality short videos from text prompts, threatening to democratize content creation and displace traditional creators. "The AI takeover of short-form content is here," the article argues, pointing to how tools like Sora could flood platforms with AI-generated vertical videos, challenging human creators for attention.
Google's Gemini AI is also entering the fray. Writing for British GQ, a columnist describes Gemini's takeover as "breaking the internet again". Gemini can generate images, text, and soon video, integrating directly into Google's ecosystem. This positions Google to compete with TikTok and OpenAI's Sora, offering creators a suite of AI tools to produce vertical content. The implications are vast: personalized video ads, automated editing, and even AI-generated influencers could become commonplace.
Vertical Video in Music and Culture
Artists are embracing the format too. Billboard reports that Ariana Grande unveiled a new vertical video for her hit "No Tears Left to Cry" alongside a rainbow mural in Los Angeles. The video, shot entirely in portrait mode, is designed for mobile-first consumption—a move that acknowledges where her fans are spending their time. Similarly, Chicago's 93XRT radio station held a "Takeover with Friko", though the event was geo-blocked in the EU. These examples show how vertical video is becoming the default for music promotion and live events.
What This Means for the Future
The convergence of vertical video and AI is creating a new media ecosystem. Platforms like YouTube, Instagram, and TikTok are in a fierce battle to attract creators and advertisers, while companies like Cloudflare ensure the technical backbone is robust. Meanwhile, AI tools like Sora and Gemini are lowering the barrier to entry, enabling anyone to produce viral-worthy clips. But this also raises concerns: job displacement for human creators, potential misinformation from deepfakes, and the homogenization of content as algorithms favor AI-generated thumbnails and hooks.
As David Pierce put it, "All these apps did have one important thing in common: they were all trying to find their identity." Now, they've found it—vertical video. The question isn't whether portrait mode will dominate, but how we'll navigate the ethical and creative challenges that come with it. One thing is clear: the screen has rotated, and there's no turning back.
