I just love BBC One idents, and this is no exception. The first link is for the ident I captured while I was in the UK, and the second is slightly longer version, and is the BBC South East varient.
BBC One is also apparently planning to ditch its current idents for a new set of promos some time in the future, should be interesting to see what they come up with. The Guardian also had an interesting rant about how idents are a waste of money.
Who or what will now replace them? Who cares? Only one thing is certain: a very large sum of money will be spent to provide something new which we could all quite easily live without, something which, you can be sure, will be scrapped after a year or so.
