Many of the UK's largest traditional media sites attracted more visitors from overseas than from within the UK in April 2007, according to comScore, writes MarketingCharts.

Online visitors from outside the U.K. outnumbered the domestic audience for websites of the BBC, the Guardian, the Telegraph, the Times, the Independent, the Daily Mail, the Mirror and the Financial Times.

"The Internet allows consumers to view relevant content at any site from anywhere in the world. It is therefore critical for publishers and advertisers to understand their global franchise - not just their U.K. audience," said Bob Ivins, managing director of comScore Europe.

"The Internet will always be a global medium, and audiences often follow interests more than national boundaries. Agencies need to be aware of this and realize that when they buy on U.K. sites they may also get an international audience," said Dan Calladine, research director of Isobar.
