S2 was a television station broadcast throughout the Scottish and Grampian ITV regions by SMG plc, the holder of the Scottish and Grampian region ITV franchises. S2, which aired on the digital terrestrial platform (branded ONdigital, at the time), was launched 30 April 1999 and closed just over two years later — as part of a deal with ITV Digital — on 27 July 2001. The channel was also broadcast on cable television services NTL and Telewest. The Grampian and Scottish franchises have operated together as STV since 2006.
