The report found that the average person spends seven hours and nine minutes a day on the internet, using a mobile phone or watching television, with the latter accounting for three hours and 38 minutes.
But the average household spend on such facilities fell to £93.63 a month; a drop of £1.53 since 2006 and £4.31 since 2004. In 2002 the average spend stood at £89.36.

Sales increased from 69,000 a month in February 2008 to 133,000 in June.
