Some DVRs have other possible 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. Certain broadcasters transmit timeshifted versions of their channels, usually carrying programming from one hour in the past, to enable those without recording abilities to resolve conflicts and those with recording abilities more flexibility in scheduling conflicting recordings.

found in favor of Sony; 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.

By 1985 cable movie channels encouraged time shifting by broadcasting films subscribers wanted for their home libraries overnight, so their VCRs could record them while they slept.

The legality of this service, for which an extra fee can be assessed, has been challenged by television broadcasters, who assert that this form of time shifting is a violation of their copyright.

Analysis

A study published in 2019 found that time shifting does not affect the size of the audience for a program which watches it live. Time shifting did, however, increase the size of the overall viewership of a program.
