A Digital Versatile Disc (DVD) is an optical disc storage format used for storing data, including movies, music, and software. Introduced in the 1990s, DVDs quickly became the standard for home video distribution, offering higher storage capacity and better video quality than VHS tapes. A standard DVD can hold up to 4.7 GB of data, while dual-layer DVDs can store up to 8.5 GB. DVDs can be played on dedicated DVD players, computers with DVD drives, and gaming consoles. While streaming services and Blu-ray discs have reduced the popularity of DVDs, they are still widely used for physical media distribution.
