The fourth series focused on the 1960s (1962 to 1969 only) and first aired on Friday nights from 10 September to 29 October 2004. It features neither 1960 nor 1961 as these pre-date the official launch of Telefís Éireann, the television arm of the national broadcaster. It was felt, presumably, that there would be too little archive material from which to make an engaging programme about these years. Indeed, the episodes covering the first half of the 1960s are characterised by extensive use of photographs and posters, as opposed to film and video footage, to represent various historical events.
