Depends on your understand of 'christian themed'. Does that include films like 'polar express' or other christmas themed films or is some degree of worship necessary?
Awww...c'mon. Whilst not being Christian myself, I quite enjoy "Carols from Kings' on the radio over Christmas.
...but - it does now beg the question - with 50% of Britons now averring that they have no religious leanings, will we be seeing even less religious broadcasts on telly?
