History in the United States

The idea of a consumer pausing a live television broadcast was depicted in popular media as early as November 1966 at the end of Season 2, Episode 12 of '' I Dream of Jeannie'', when character Major Nelson asked his genie to pause a live broadcast of a football game so that they could continue to watch it from that point after a grocery shopping trip.

s encouraged time shifting by broadcasting films subscribers wanted for their home libraries overnight, so their VCRs could record them while they slept. Some providers, such as satellite TV companies, have introduced digital video recorder (DVR) features, thereby allowing consumers to skip over advertising entirely when watching a program which has been recorded to their DVR. 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.
