The ITV television network of the United Kingdom is divided into a number of geographical regions.
Regional and sub-regional news and weather coverage may extend to include overlap areas.
The other ITV channels such as ITV2, ITV3 and ITV4, are not divided into regions, and each broadcasts a single service across the country.
Each regional station was responsible for its own branding, scheduling and advertising, with many peak-time programmes shared simultaneously across the whole network.
By 2002, all regional companies in England and Wales were owned by either Granada plc or Carlton Communications.
Two years later, Granada and Carlton merged to form ITV plc.
Similarly in Scotland, both the Scottish and Grampian regions were rebranded in 2006 as "STV" at all times.
