As usual with the new series of Doctor Who, there is a Christmas special. This special feature length episode usual bridges the gap between seasons and is a good way to resolve cliffhangers.
With the Doctor Who franchise encompassing The Sarah Jane Adventures and Torchwood, on top of the main series, there is a lot of Doctor Who available for fans. I believe that the Doctor has never been this popular. A new K-9 show for kids will air on Australian television in July 2008.
