Yeah we don't get the Sky stations here in the US. I always assumed it was something similar top ABC or NBC here in the states. I've heard of Skynews. I think it would be hard to devote and entire television station to Christmas stuff (even if its only annually) I know ABC gets a lot of Protest for their "25 Days of Christmas" programing on ABC family.
"I have always thought of Christmas time, when it has come round, as a good time; a kind, forgiving, charitable time; the only time I know of, in the long calendar of the year, when men and women seem by one consent to open their shut-up hearts freely, and to think of people below them as if they really were fellow passengers to the grave, and not another race of creatures bound on other journeys." ~Charles Dickens
