Having been Head of Serials from 1997 to 2000, Jane Tranter was made Head of Drama in 2000. Tranter's era from 2000–06 saw a return to longer-run episode series, with programmes such as "Spooks" being given longer second runs following successful debut seasons. Recent years have also seen a huge increase in continuing drama output, with "EastEnders" gaining a fourth weekly episode to add to the third added during the mid-1990s, and "Casualty" and its spin-off series "Holby City" (1999–present) turning from regular seasonal shows to year-round soap opera-style productions. These moves have been criticised in some quarters for filling the market with insubstantial populist dramas at the expense of 'quality' prestige pieces, although there have been several notable drama serial successes, such as Paul Abbott's "State of Play" (2003) and the historical drama "" (BBC Northern Ireland - 2004).
