Up to 60% of the Republic of Ireland could receive UK channels via spillover or via cable. Cable in the republic was only permitted in areas of spillover up to the mid-1980s, to provide viewers with better reception of channels they could already receive over the air. Hence RTÉ 2 was aimed at those that did not have the UK channels. To this end one of their main remits was the re-broadcasting of UK programming to Irish audiences, that would not otherwise be seen on RTÉ 1.
