The serial format changed for the 2005 revival, with each series usually consisting of 13 45-minute, self-contained episodes (60 minutes with adverts, on overseas commercial channels), and an extended episode broadcast on Christmas Day. Each series includes several standalone and multi-part stories, linked with a loose story arc that resolves in the series finale. As in the early "classic" era, each episode, whether standalone or part of a larger story, has its own title. Occasionally, regular-series episodes will exceed the 45-minute run time; notably, the episodes "Journey's End" from 2008 and "The Eleventh Hour" from 2010 exceeded an hour in length.
