Tim O’Sullivan (1991) in the UK and Lynn Spigel (1992a; 1992b) in the USA have each shown how the performance of television viewing had to be ‘learnt’ back in the 1950s, when there was uncertainty about the ways in which the technology ought to be incorporated into day-to-day, domestic life. Some consumers were still unsure as to which spatial ‘region’ of the household television was to be placed in, and precisely how it was to be watched. Alongside Scannell, another theorist who emphasises the ordinariness of broadcasting, focusing on the medium of television, is Roger Silverstone.

Global climate change and its accompanying risks, for example, probably result from our intervention into the environment. They aren’t natural phenomena. Science and technology are inevitably involved in our attempts to counter such risks, but they have also contributed to creating them in the first place. We face risk situations that no one in previous history has had to confront – of which global warming is only one. Many of the new risks and uncertainties affect us no matter where we live, and regardless of how privileged or deprived we are.

Considering the emergence of ‘rolling’ news channels such as CNN, Sky News and the BBC’s own News 24 digital station, Richardson and Meinhof (1999: 8–9) observe how: 24-hour news channels address the ‘need’ for TV news-on-demand, and thus break with the tradition which ties news programming to specific times of the day. This is one aspect of changes in scheduling … which arguably give a different kind of basis for the temporal relations between TV and its audiences. Television becomes less important than heretofore in constructing ‘dailiness’ on the basis of predictably different ‘mornings’, ‘afternoons’ and ‘evenings’.
