A DVD, or Digital Versatile Disc, is a type of optical disc used to store data, including movies, music, and software. It was introduced in the mid-1990s and quickly became popular for home entertainment. DVDs can hold much more information than traditional VHS tapes, allowing for better video and audio quality. To play a DVD, you need a DVD player, which reads the disc and sends the content to your television. Many people enjoy collecting DVDs of their favorite films and shows, as they often come with special features like behind-the-scenes footage and commentary from the creators.
