S4C

The first television channel to be aimed specifically at a Welsh-speaking audience, S4C is the fourth-oldest television channel in the United Kingdom, after BBC One, ITV and BBC Two, (Channel 4 was launched in the rest of the UK one day later.)

When first established, the channel 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 television arrived several years later, S4C added a second, 100% Welsh-language service, called S4C Digidol ("digital"). With the completion of the digital switchover in Wales on 31 March 2010 S4C's bilingual analogue channel closed, and what had been S4C Digidol became the default S4C channel, available on Freeview, satellite and cable, and broadcasting entirely in Welsh.
