Undercurrents is an alternative video news network which began with the UK distribution of videotapes shot by volunteers. It has since expanded to include a web presence, for volunteers, and a film festival, Beyond TV.
Undercurrents magazine was started as a medium for radical views on scientific and technological subjects; it was published in England between 1973 and 1984: 63 editions altogether. For much of that period it appeared every two months and the circulation peaked at 7,000 in the late 1970s. It existed to promote Alternative technology - an infinitely elastic concept embracing almost every subject that so-called 'straight' scientists weren't interested in.
