This was on BBC Radio 4 this morning.

Apart from the fact that the BBC, could stay in Britain to see Tolkien's Middle earth(sic), I thought it was quite an interesting programme, and good luck to them on continuing to promote "Hobbiton".

Nancy Nicolson travels to Middle Earth(sic) to discover how a remote corner of a 1250-acre New Zealand sheep station became one of the most famous pieces of farmland in the world.
When location scouts settled on the Alexander family farm near Matamata, just south of Auckland, as the location for The Lord of the Rings and The Hobbit movies, it changed the fortunes of the traditional sheep unit which is run by two brothers.
Now Craig Alexander continues to run the sheep enterprise while his brother Russell manages Hobbiton, a global tourist destination attracting 500,000 visitors a year.
Nancy learns about the economics that have driven New Zealand sheep farmers to become more efficient; hears how the army was employed to drive roads into remote land and visits some of the Hobbit holes.
