One of the Sky Atlantic premieres this year is now going to be shown, in full, on Sky Living HD from August 20th. Now that makes sense: the show got good initial reviews but was something of a ratings flop on Sky Atlantic (as are most), so putting it on a channel with a wider audience will appease advertisers and mean Sky gets more air time for its investment in the show.
So will Sky do similar with other Atlantic series? I guess Game of Thrones is unlikely, but maybe the homegrown stuff like Adam Buxton's Bug or the Kathy Burke series Walking and Talking? They always sounded more like Sky1 series to me than Atlantic.
There are rumours of more HD channels coming to Virgin Media in the autumn, but I've not heard anything definite yet. ITV2, 3 and 4 are obvious candidates, but anyone banking on seeing Atlantic or F1 is I fear going to be disappointed.
