Computers, tablets, smartphones and mobile phones enable people to act across contexts. For individuals born during the first half of the twentieth century, these social infrastructures for agency arrived late in the life course. This article presents an analysis of a set of interviews that were thematically coded to reveal ways in which the infrastructures figured in reflexive practices among older single-dwelling women. The interviews were patterned by the shared image of a ‘media world’ and the hypothesis of the indispensability of newer media for living a socially integrated life in today’s society. Control of media connected with feelings of dis- or empowerment; ultimately media amplified the participants’ feelings of being autonomous actors. I argue that the newer media infrastructures extend the scope and need for reflexivity and augment the reflexive ageing associated with the continued activity and autonomy of the third age.
