Many mobile carriers enforce daily or monthly data limits. A 300MB download ensures that movie lovers can enjoy their favorite films without exhausting their entire data allowance in a single sitting. The Digital Ecosystem: Navigating the Landscape Safely

Most 300MB files were optimized for standard definition (480p) or entry-level high definition (720p). On smaller screens, such as a 14-inch laptop or an early smartphone, a well-encoded 480p or 720p video looked remarkably sharp. Encoders carefully balanced the bitrate—the amount of data processed per second—to ensure that fast-moving action scenes didn't devolve into blocky artifacts.

Sites such as WorldFree4u and 300mbmovies4u act as repositories for these encodes.
