I was never keen on these balloon idents towards the end. I wonder if these were Heggessey implemented?
Unless I'm mistaken, Peter Salmon was still the controller of BBC1 when the "lifestyle" balloon idents were introduced in early 2000.
Most, if indeed not all, of the regular idents from '98, '99 and 2000 had the balloon digitally inserted, instead of being filmed with the rest of the scenery.
