Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over-the-air by radio waves and received by a television antenna ; or satellite television, in which the television signal is transmitted over-the-air by radio waves from a communications satellite and received by a satellite dish on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation.

TV Times is a British television listings magazine. From 1955 until 1991, it was the only source of seven-day listings for ITV and, from 1982, Channel 4. The magazine did not circulate nationally until 1968 as some regional stations opted to produce their own listings publications. Until the market was deregulated, its nearest rival was Radio Times – owned then by the BBC and at the time the only source of weekly BBC television and radio schedules. However the two magazines were very different in character, and viewers wanting the full listings for the coming week were required to purchase both publications. The TV Times branding was also used for several broadcast spin-offs on ITV, including the Miss TV Times and The TV Times Awards during the 1970s and 1980s.
