The series, which has drawn comparisons with The X-Files, had a shaky premiere last month but has since ascended in the ratings. Four weeks in, it has averaged 10.7 million viewers in its Tuesday 9pm timeslot.

Exec producer Abrams added: "As with many new series, Fringe is just starting to find its groove. Knowing we'll be around beyond the first thirteen episodes means we'll get to realise the full potential of the show, and for that we are extremely grateful."
Fringe starts in the UK on Sky1 this Sunday.
