Very rarely does a television series put out a standalone episode that is not only brilliant in and of itself, but also stands above pretty much every episode of that series. And yet, with the tenth episode of the third series, Doctor Who did just that with "Blink." Even more remarkable is that this episode barely featured the Doctor or then-companion Martha Jones. It had become common, due to the tight production schedules, for an episode each season to barely feature the Doctor, but this one absolutely blew our minds.

And apparently voices that matter agreed, because writer Stephen Moffat was just awarded the prestigious Hugo Award for short form dramatic presentation for "Blink." I have to figure it's a large part of why he's been selected to take over as lead writer and executive producer of Doctor Who from Russell T. Davies when the show returns for its fifth series in 2010. Based on this one episode alone, the show couldn't be in better hands.

Back in February we reported on rumors that the BBC would be distributing some of its more popular shows, including Doctor Who, via iTunes in the U.S.. Well, they are rumors no more. To coincide with this week's appearance of the BBC at the San Diego Comic-Con, the BBC is releasing Doctor Who for purchase and download from the iTunes store.

Now, before you get all crazy and start searching for episodes of the show that featured Peter Davison as the fifth Doctor, the episodes that are being offered are from the new series only. And, you can't purchase and download shows from the current fourth series. However, you can download series one through three. This means you get both Christopher Eccleston as the gritty Doctor and David Tennant as the more exuberant Doctor.
