Though Sky News is not set to go high definition until Spring 2010, that doesn't mean it can't do "specials" in HD.
Michael Jackson's memorial service, for example, which takes place tomorrow.
Kay Burley will present "Michael Jackson: The Farewell" from 5.30pm BST, with commentary from US correspondents Robert Nisbet and Greg Milam.
As Sky News HD currently doesn't exist, the HD version will be simulcast on Sky Arts 1 HD, as well as Sky News and Sky Arts 1 in standard definition.
There's a bit more info over at the Sky News Editor's blog.
Update: For those without Sky, you can also catch a special programme on Five. "Michael: The World Says Goodbye" starts at 6.30pm and will be hosted by Matt Barbet with additional reporting by Five's Chief Correspondent Jonathan Samuels.
There will also be coverage on BBC2 and the BBC HD channel from 6pm (thanks Max for the heads up on this late schedule change).
