These days, you can watch party political broadcasts before they've even been broadcast, as with this one from the Labour Party that's scheduled to appear on television tonight.
It has at least two irritating features that I've blogged about before. One is ghastly background musak - for more on which, see Is the sound of music on TV getting more and worse?
The other is that we no longer have to put up with television reporters telling us what politicians are saying during speeches in the background but can now listen to a party leader doing the voiceover to films of his own silent speeches in the foreground - for more on which, see Politicians and broadcasters in the UK: collaboration or capitulation?
