ITV London

ITV London is the on-air brand name used by ITV Broadcasting Limited for the two Channel 3 broadcast franchises, Carlton Television (weekdays) and London Weekend Television (weekends) in the London ITV region.

History
ITV London was formed on 28 October 2002 as a unified on-screen brand for both of the Carlton and LWT franchises, running on Weekdays and Weekends respectively. It replaced the unique branding used by both franchisees with a unified service, offering the same service and news all week round. Legally, both franchises remained separate, however are run by the same operating board and from the same facilities.

ITV London is also unique in that it supplies the network feed for the other franchises and is the sole alternative ITV region to Sky Digital customers. This service, available on channel 993, is so that audio description services, which are only carried on the London variant on satellite, are readily available to all viewers. Other regional variants are available by searching, however the region is the only one to be given an exclusive EPG slot.

Studios
ITV London is based at The London Studios, on the south bank of the River Thames, the former home of Weekend franchise London Weekend Television. The centre was chosen due to both companies presence in the centre; Carlton having leased space within the facility, alongside GMTV, since 1993. The contracted news service London News Network was also based, recorded and broadcast from the centre.

Identity
The services' on-screen identity has been generic throughout its existence, and has used no on-screen branding to identify it as ITV London. Since launch, the region has seen the plain generic idents seen by the rest of the country, without any regional variance identifying it as London; the other regions at this time received a regional ident with the region name below the ITV1 Logo. Any reference to the service being in London is made in the voiceover alone, or through the programme titles, such as London Tonight.

Some identity remained on the regional programming end boards however, as each company still produced programmes for the region: Carlton used a red and orange version of their star idents used prior to 2002 with the caption A Carlton Production, with For London added for regional programming, while LWT used a generic purple caption with their logo added into the background. The LWT logo was also laid out in a purple box clearly at the top, with the caption An LWT Production beneath and the Granada plc logo at the bottom. These endboards lasted until 2 February 2004, when ITV plc was formed and both regional captions were replaced by a generic ITV London logo and An ITV Production caption against a blue squared background. This was replaced in 2006 by a blue caption featuring the new ITV1 logo with the words "a production for" above it.

Today, the only distinction between the two original regions on-screen is that local weather forecasts broadcast from Friday night to Sunday is branded as London Weekend Weather, and is sponsored by a different company to the weekday forecasts.

Productions
ITV London itself doesn't make any programmes, as all productions were completed by external companies, Carlton, LWT or London News Network. The News and Sport for the region continued to be provided by LNN until 1 March 2004, when ITN took over production of London Tonight, resulting in the move of the programme from The London Studios to ITN's headquarters at Gray's Inn Road. Other regional programmes continued to be produced for the region by the two legal franchises, Carlton and LWT, and the companies were accredited at the end of the production until 2004, when it was replaced by a ITV London caption for both companies following the ITV plc merger.
