Vertical Video Format Has Taken Over Social and Streaming Platforms

A new analysis from The Verge examines how vertical video has become the dominant format across major digital platforms. Historically, platforms like YouTube, Instagram, Facebook, and Twitter each had distinct identities and content formats. Over time, the rise of short-form vertical video — popularized by mobile-first consumption — has reshaped how content is created and distributed. The shift reflects a broader convergence among social media and streaming services, all now competing in the same vertical video space. The trend marks a significant departure from the era when each platform had a clearly defined and separate purpose.
