When first established, the channel — initially broadcast on analogue television — was bilingual (Welsh and English) outside peak hours, with English-language content consisting of the simultaneous or deferred transmission of programmes from Channel 4 (analogue reception of which was unavailable in most of Wales). When digital terrestrial television arrived several years later, S4C added a second, full-time Welsh-language channel called S4C Digidol ('digital') on 1 November 1998. With the completion of the digital switchover in Wales on 31 March 2010, which made English-language Channel 4 available across Wales, S4C's bilingual analogue channel closed; what had been S4C Digidol became the default S4C channel, available on Freeview and pay-television, and broadcasting entirely in Welsh. S4C does not commission programming in English, but when English is used on the channel, it is left untranslated. Moreover, the channel includes an English subtitle-track available for some programmes, which viewers can access using their television set's remote control.
