NetImperative reports that the U.K.'s internet use is enormously skewed to its capital city London. Studying just where ads are appearing when they pop up on British screens, NetImperative found that second and third place cities Manchester and Birmingham took only 5.1 and 3.6 percent respectively. The study used a British banner server, taking data randomly from ten days in January. London accounted for 48 percent of the traffic.
