VHS became the leading consumer tape format for home movies after the "videotape format war", though its follow-ups S-VHS, W-VHS and D-VHS never caught up in popularity. In early 2000s in the prerecorded video market, VHS began to be displaced by DVD. The DVD format has several advantages over VHS tape. A DVD is much better able to take repeated viewings than VHS tape, which can crack or break, which makes DVDs a better format from a rental store's perspective. As well, whereas a VHS tape can be erased if it is exposed to a rapidly changing magnetic field of sufficient strength, DVDs and other optical discs are not affected by magnetic fields. Even though DVDs do not have the problems of tapes, such as breakage of the tape or the cassette mechanism, DVDs can still be damaged by scratches. Another factor for movie rental stores is that DVDs are smaller and take less space to store. DVDs offer a number of advantages for the viewer: DVDs can support both standard 4x3 and widescreen 16x9 screen aspect ratios and DVDs can provide twice the video resolution of VHS. As well, a viewer who wants to skip ahead to the end of a movie can do so much faster with a DVD than with a VHS tape (which has to be rewound). DVDs can have interactive menus, multiple language tracks, audio commentaries, Closed Captioning and subtitling (with the option of turning the subtitles on or off, or selecting subtitles in several languages). Moreover, a DVD can be played on a computer.
