Killinaskully was produced by Shortt's own company and was broadcast by RTÉ as part of their Sunday night schedule from 2004. All five series are available on DVD and have since been released in box set format. The show's fifth and final series, began transmission on 28 September 2008. It ceased on 2 November 2008, although the traditional special at Christmas time aired as normal the following month; in 2008 there were two such specials. Despite having a weekly audience of 800,000, Shortt has stated that the fifth was the final series as he wished to concentrate on the development of a new show with a new style, characters and storyline. Nevertheless, RTÉ continue to rerun the series as summer filler.
