The Corporation has been threatening to cut the UK's first dedicated-HD channel from the airwaves for what seems like forever. Now, finally, we've got a date. BBC HD will cease to be at 6am on Tuesday March 26th, straight-up replaced by BBC Two HD.
In all honesty, it's not going to make much of a difference. The BBC's changed the way BBC Three and Four operate as feeder channels for One and Two, which means all the HD shows you know and love will still be shown in HD on BBC One HD and BBC Two HD. In fact, it'll make things a little easier to work out, because everything that's on BBC Two will be shown in HD, rather than just most things, with the odd exception here and there.
So there you have it, March 26th will mark the end of an era -- the death of the UK's first dedicated HD channel, and the birth of BBC Two HD.
