VHS, or Video Home System, is a format for recording and playing back video content. Introduced in the 1970s, it became popular for home video use, allowing people to watch movies and record television shows on tapes. The VHS tapes are rectangular and contain magnetic tape, which stores the video and audio information. The format was widely used until the early 2000s when digital formats like DVD and Blu-ray began to dominate the market. Despite its decline, VHS remains a nostalgic symbol of home entertainment for many, representing a time when video rental stores like Blockbuster were popular.
