Time shifting is the recording of television shows to some storage medium to be viewed at a time more convenient to the consumer.
In recent years, the advent of the digital video recorder (DVR) has made time shifting easy, by using a program guide and recording shows onto a hard disk. Some DVRs have other possibile time shifting methods, such as being able to start watching the recorded show from the beginning even if the recording is not yet complete. In the past, time shifting was done with a video cassette recorder (VCR) and its timer function, in which the VCR tunes into the appropriate station and records the show onto video tape.
The Sky+ service in Ireland and the UK allows you to timeshift. TiVo, DirecTV and other US cable or satellite subscription services offer PVR set top boxes, often for an additional monthly fee.
In cable television broadcasting, time shifting may also refer to the availability of network affiliates from different time zones, serving a similar function of making television programs available at multiple times throughout the day.
History
The legality of time-shifting programming in the United States was proven by a landmark court case of Universal Studios versus Sony Corporation (Sony v. Universal), when Sony argued successfully that the advent of its Betamax video recorder in 1976 did not violate the copyright of the owners of shows which it recorded.
In 1979, Universal sued Sony, claiming its timed recording capability amounted to "copyright infringement". However, a district court found that noncommercial home use recording was considered fair use and ruled in favor of Sony. In appeals, the United States Court of Appeals reversed this decision in 1981 giving the edge to Universal, but the Supreme Court of the United States reversed it yet again in 1984, and found in favor of Sony 5-4. The majority decision held that time shifting was a fair use, represented no substantial harm to the copyright holder, and would not contribute to a diminished marketplace for its product. Today, this is widely referred to as the "Betamax case" or "Betamax decision".
