Facebook.com was the fastest growing property in the U.K. The social
networking site grew 18.3 percent in August to reach just under 9 million
unique visitors. The site has experienced a dramatic 2,167 percent growth
within the U.K. since September 2006, when it made the decision to open up

requiring a valid email address from a university or a selected group of
secondary schools and businesses. During the same period, traffic to the site
has increased strongly across Europe, where it has grown by 2,446 percent to
reach 13.2 million unique visitors.

British Sky Broadcasting experienced a 10 percent growth in traffic,
reaching 7.4 million unique visitors. This increase was sparked by interest
in skysports.com, thanks to the onset of the new football season.
Premiumtv.co.uk, also benefited from the start of the football season. The
company, which manages the digital rights of football in the U.K. and
produces multi-platform club specific content, enjoyed a 17.1 percent growth
