TVCatchup is an internet television service for viewing certain UK channels from free-to-air digital terrestrial and satellite broadcasters live without the use of a television receiver. The service re-broadcasts BBC, ITV, Channel 4, Channel Five and free to air Sky channels. Initially the legality of the service was questioned causing it to be suspended. The service was relaunched minus the network PVR functionality offering a roster of TV channels upon free registration. As the service permits the viewing of live television channels a TV licence is required. The service is only accessible in the United Kingdom and according to TVCatchup's own forums, the website has stringent IP monitoring facilities that they use to detect and block multiple accesses from the same IP as well as all proxy and VPN access. The service is funded by advertising, with a pre-roll advertisement preceding the live channel stream.

Launched in late 2007, the site was initially conceived as an online PVR service, where users could select shows from one of 30 free-to-air channels to record up to one week in advance of their broadcast. These online recordings could not be legally downloaded by the user, merely viewed online. They could however be temporarily lent to other users who had not recorded the show, for a period of up to 60 days after their broadcast, when they were then removed from the site. The site differed from broadcaster services such as the BBC iPlayer, 4oD and Demand Five in that content was not instantly available to users, but had to be recorded in advance or requested. Just like a physical PVR, users were also able to create a series-link so that all future broadcasts of, for example, their favourite soap or documentary, would automatically be recorded.
