Since 27 October 2002, on all ITV plc-owned franchises, regional programming has been preceded or plugged by an oral regional announcement, in the format ITV1 "regional brand"; e.g. ITV1 Granada. In English regions, up until 13 November 2006, regional names were also superimposed (post-production) on these idents below the ITV1 logo, but this practice has since ceased. ITV Wales remains unaffected, and still continues to use dual-branding across all of its on-screen presentation. Despite the lack of regional names on screen, the regional name is usually spoken by the continuity announcer prior to local programmes. After ITV's unification in 2002, the two London franchises, Carlton Television and London Weekend Television were merged into a single entity, ITV London, while the Wales and West franchise lost its official identity, and instead was substituted with ITV Wales and ITV West on-air, with no reference linking the two together (the licence was formally split in two by Ofcom from 1 January 2015).
