Television operator Sky is reporting decreasing half-year profits, as extra costs offset the gains from increased subscribers.

The delayed releases of the new Sky Box and Sky Pod have created extra operating costs for Sky.

CEO Sophie Maloney says that Sky has retained solid subscriber growth and they've secured all the content they targeted.

"Our delay in delivering the new Box and the new Pod has meant we've had some additional costs to continue with the Vodafone TV platform. That's had a slight impact on our profit number but overall, we're headed in the right direction."
