Each episode, running for about 25 minutes, reviews the events of a particular selected year, from 1962 to 2009. News archive footage features, along with subtitles as the means of narration, to recount important national and international events of the time. Music from the selected year plays across the footage, with occasional scenes of live performances or music videos, often (but by no means exclusively) by an Irish artist. No advertisements are shown during the broadcast (apart from the occasional old advertisement dating from the relevant year). Each decade takes at least eight months to make.
