Supernanny and New Tricks production firm Shed Media shrugged off a "turbulent" broadcasting market today with new BBC dramas and American versions of its UK hits set to drive growth.

The firm said recently announced BBC drama Young James - based on the early years of vet James Herriot - and the continued success of the US versions of Supernanny and ancestry show Who Do You Think You Are? left it well placed for the rest of the year.

Shed, which recently agreed a £100 million takeover by Hollywood media giant Time Warner, posted a 22% hike in pre-tax profits to £6.2 million in the six months to June 30, up from £5.1 million last year.

"The UK broadcast market remains turbulent with significant changes occurring across all the major broadcasters. Against this backdrop, Shed has strengthened its position," chairman Heather Rabbatts said.

As of this month, Shed Media has already secured 317 hours of commissioned TV production - 93% of its targeted production revenue for the year.

Chief executive Nick Southgate added: "We have seen an improved performance in our UK business, where all our major brands have been secured for further series. The US operation has continued to thrive with a number of new projects now in production."

In the first half of the year, turnover rose 27% to £59 million, up from £46.5 million last year. During this period, the group delivered 153 hours of programming comprising 84 hours from the UK and 69 hours in the US.

British dramas New Tricks and Waterloo Road were a success for the group in the first half, as were factual shows The Choir and World’s Strictest Parents.

The firm - which made Footballers’ Wives for ITV until 2006 - said it had secured new other high-profile commissions such as Turn Back Time: The High Street, for the BBC, and We Built the Titanic, for Channel 4.
