This article reviews the development history of video movements, the core components of video playback devices, which evolve with electronic technology advancement and market demand changes. In the late 1990s-early 2000s (rudimentary stage), they featured small 2.4-inch screens, 128MB-512MB memory, and single button control (basic functions like play/pause). From the mid-2000s to early 2010s (rapid iteration stage), 4.3-inch/5-inch screens became mainstream, memory expanded to 1GB-8GB, and magnetic/light control were added, with enriched buttons (volume adjustment, etc.). Since the mid-2010s (intelligent stage), 7-inch/10.1-inch large screens prevailed, memory reached up to 16GB, and remote/mobile APP control was integrated, supporting customized buttons. The article notes their progress ties to tech innovation, predicting a more intelligent, HD, and integrated future driven by 5G and other technologies.
