Zoom

Zoom won on a single interaction: joining a meeting is nearly frictionless, a link opens straight into video where rivals demanded accounts and setup. Its core screen is the toggle between gallery view, the grid of equal tiles, and speaker view, which promotes whoever is talking, a layout decision that quietly governs whether a meeting feels hierarchical or flat. The bottom control bar is the whole product, with mute, video, share, reactions, and the dreaded leave button anchored in muscle memory. Screen sharing is the strong center, with annotation and remote control layered on. Webinar and breakout modes show their seams, with host controls buried in menus. Virtual backgrounds and the hand-raise became cultural shorthand. The design optimizes for the meeting moment, not the messaging around it.
