Following the start of its TV airing over the weekend, the first episode of season five of TV show Lost is now the first TV programming available in HD on the iTunes Store in the UK.

An HD episode of the show is priced at £2.49 and comes complete with an iPod-ready version with a file size and resolution that's suited to smaller screens.

The whole series will set fans back over £40, with more high def programming promised to follow.
