What provision is there for regional variations on Freeview?
Nowadays, regional variations are used for little else other than regional news bulletins and regional advertisements. BBC1 is fully regionalised on Freeview. I do not know whether sub-regions are provided for. BBC2 is not yet regionalised on Freeview, a fact which sometimes causes great annoyance to viewers when regional programmes are put on BBC2. ITV1 is fully regionalised on Freeview. I suspect that some of the other major commercial channels might be regionalised, in order to be able to insert regional advertisements. BBCi, the BBC’s digital text system, does not appear to be regionalised yet, judging by its television schedule listings. Teletext on Freeview channel 100 is fully regionalised.
