The cult television programme, which follows the behaviour of a group of people living together in isolation from the outside world for up to nine weeks, already attracts millions of viewers to its late night TV broadcasts.
But with live transmission available 24 hours a day via the internet, the Big Brother website is proving popular with followers, boasting 700,000 visitors (6.9 per cent of all home internet users) in July alone.
According to Netvalue, this activity has propelled Big Brother into the top 50 most frequently visited websites in the UK, while Demon.net, the company which provides the Big Brother site with its video-streaming, has scooped the number one spot as the most popular service of its kind in the country.
Channel 4's website, which offers a direct link to the Big Brother pages, has also benefited from the increased internet activity, recording a 5.3 per cent jump in its website reach for July.
The findings also indicate that 60 per cent of all visitors to the Big Brother site are aged 34 and under, while two in three visitors are male.
