Category talk:ITV (TV network) original programming

What about adding categories of programmes made by each region?
Shouldn't there be new sub categories be created in addition to list of ITV programmes such as: Category:Granada television programmes, Category:Thames television programmes, Category:LWT television programmes etc? Surely including such categories would help to give more clarity with regards to which franchise produced which programmes. --Wrh1973 19:07, 1 March 2007 (UTC)
