Dracula, the BBC and Netflix’s blood-soaked retelling of Bram Stoker’s mythical vampire story, has sunk its teeth into a much-improved audience with the addition of catch-up and online viewing in the UK.

The seven-day rating — including mobile, tablet and computer viewing — for the first episode of Hartswood Films’ drama stood at 7M viewers, according to BARB figures provided by the BBC. This was nearly double Dracula‘s overnight audience of 3.6M.

The three-part season, created by Sherlock writers Steven Moffat and Mark Gatiss, was aired on consecutive nights in the UK, starting on New Year’s Day. It launched globally on Netflix on January 4.

Dracula has also helped boost iPlayer, the BBC’s streaming service. The gothic drama’s first episode has racked up 2.4M requests on iPlayer, while 1.8M and 1.3M views have been registered for episode two and three respectively.
