The personal video recorder (PVR), also called digital video recorder (DVR) or digital personal video recorder, is a consumer electronics device that records television shows to a hard disk in digital format. Since first introduced by TiVo at the Consumer Electronics Show in 1999, PVRs have steadily developed complementary abilities, such as recording onto DVDs.
