Abstract: Computing platforms and methods for dynamic presentation of graphical and video content are disclosed. Exemplary implementations may: provide, in a static browsing state, a static image associated with underlying video content; in response to an extended focus on the static image for a first threshold amount of time, expand a visual tile to a widescreen aspect ratio while remaining in the static browsing state; after a second threshold amount of time, initiate a dwell browsing state in which dwell tile content is provided in the expanded visual tile, while other content remains in the static browsing state; in response to a determination that the playback device supports a dwell video mode, play a video asset within the expanded visual tile; and in response to a determination that the playback device does not support the dwell video mode, provide an alternate non-video visual asset within the expanded visual tile.
