Time–space compression (also known as space–time compression and time–space distantiation), first articulated in 1989 by geographer David Harvey in The Condition of Postmodernity, refers to any phenomenon that alters the qualities of and relationship between space and time.
Time–space compression often occurs as a result of technological innovations that condense or elide spatial and temporal distances, including technologies of communication (telegraph, telephones, fax machines, Internet), travel (rail, cars, trains, jets), and economics (the need to overcome spatial barriers, open up new markets, speed up production cycles, and reduce the turnover time of capital). According to theorists like Paul Virilio, time-space compression is an essential facet of contemporary life: "Today we are entering a space which is speed-space ... This new other time is that of electronic transmission, of high-tech machines, and therefore, man is present in this sort of time, not via his physical presence, but via programming" (qtd. in Decron 71). Virilio also uses the term dromology to describe "speed-space."
Doreen Massey maintains this idea about time-space compression in her discussion of globalization and its effect on our society. Similar to Virilio, she states that because our world is "speeding up" and "spreading out", time-space compression is more prevalent than ever as internationalization takes place. Cultures and communities are merged during time-space compression due to rapid growth and change, as "layers upon layers" of histories fuse together to shift our ideas of what the identity of a "place" should be. 
Theorists generally identify two historical periods in which time–space compression occurred; the period from the mid-19th century to the beginnings of the First World War, and the end of the 20th century. In both of these time periods, according to Jon May and Nigel Thrift, "there occurred a radical restructuring in the nature and experience of both time and space ... both periods saw a significant acceleration in the pace of life concomitant with a dissolution or collapse of traditional spatial co-ordinates" (7).
For Moishe Postone, Harvey's treatment of space-time compression and postmodern diversity are as merely reactions to capitalism. Hence Harvey's analysis remains "extrinsic to the social forms expressed" by the deep structure concepts of capital, value and the commodity.
For Postone the postmodern moment is not necessarily just a one-sided effect of the contemporary form of capitalism but can also be seen as having an emancipatory side if it happened to be part of a post-capitalism. And because postmodernism usually neglects its own context of embeddedness it can legitimate capitalism as postmodern, whereas at the level of deep structure it may in fact be more concentrated, with large capitals that, accumulate rather than diverge, and with an expansion of commodification niches with fewer buyers.
Postone asserts one cannot step outside capitalism and declare it a pure evil, or as a one-dimensional badness. For Postone, the emancipatory content of such things as equal distribution or diversity are potentials of capitalism itself in its abundant and diverse productive powers. It misfires however, when a form of life such as postmodernism takes itself for being the whole when in fact it is just another appearance of the same capitalist essence.
