The average Brit owns £3,000 worth of gadgets, says Sky HD.

Research by the broadcaster revealed that on average people only know how to use around half of the functions available on their gadgets.

Sky said the 'gadget gap', or the difference between the amount spent on gadgets and the value of the function they actually use on those devices, amounts to £52bn.

The research also shows that Brits are not as tech-savvy as they might have hoped.

Nearly half (47 percent) said they didn't know that to experience the benefits of an HD-ready TV, they had to connect the display to an HD device such as a Blu-ray player or HD set-top box.

Nealy two thirds of women will refer to the instruction manual if they don't know how to work a gadget, while only 54 percent of men said they'd do the same.

Furthermore, just 25 percent of men will seek help from someone else, compared to 47 percent of women.
