People watch more TV than they think

People are buying bigger televisions and watching them more, a survey shows.

Researchers who questioned more than 2,000 adults also found they watched on average an hour a day more TV than they thought they did. Figures from the Broadcasters' Audience Research Board showed most people watched more than 30 hours of television a week.

But the survey found that when asked to say how much TV they watched, most said it was less than 20 hours.

Figures also showed more than 9.5 million television sets were bought in 2010, double the number in 2002. Two million sets with screens 40in or larger sold in 2010, compared with fewer than 600,000 in 2006.
