By the end of the 1980s the total number of UK TV licences was around 19 million. During the 1980s and 1990s cable and satellite TV both played an increasing role in the media in Britain, providing a greater choice for those prepared to pay for it. One of the biggest changes in the way people in Britain spend their leisure time in recent years has been an increase in the amount of time spent watching television. The average winter viewing figures are now about twenty-eight hours per week. As you might expect, television viewing is less popular in summer than in winter and more popular with passengers than any other age group. Viewing also varies according to social classes, with professional and managerial classes watching less than the unskilled and the unemployed. On average, women watch more than men. British TV has an international reputation for producing programs of a high quality, such as documentaries, nature programs, comedies and drama series and according to the government there should be a combination of “competition, quality and choice” in any plans for the future of TV. However, not everyone agrees that more TV means better TV and it has been argued that the standard programs with a mass appeal such as soap operas, quiz shows and situation comedies are not very high. “Minority programs”, such as many of those broadcast on BBC 2 and Channel 4, might disappear.
