Still no word regarding it turning up on Virgin Media, but I've just noticed that Sky's Now TV is still offering the Entertainment Package (Sky Atlantic et al) for just £4.99 a month. I thought it was an introductory offer but it's still a fiver. For me, that's worth it, especially given the line up this spring.
Anyway, for those craving Sky Atlantic Now TV's On Demand includes all three seasons of Game of Thrones, all six of Mad Men and the much talked about True Detective. I'm impressed and will be signing up again in April for my annual fixes of GoT and Mad Men (there's been little to lure me these last few months).
It's not HD but the SD's good and I've had no picture problems. You can get a NowTV box for £9.99 or LG Smart TVs and XBox owners have it as an App.
