 ITV has traditionally included more regional variations than the BBC, though since consolidation and majority ownership by ITV plc regional variations on the network are far fewer, and often no more than the minimum requirements as set by Ofcom.Channel 4 and Channel 5 provide no regional variations for programming or continuity, but do sell localized advertising.A notable exception was S4C, a channel in Wales which broadcast in place of Channel 4, and primarily broadcast Welsh-language programming of interest to the local audience, as well as programming acquired from Channel 4 (but not always in pattern).
