IN ASSOCIATION with Repskan.com, City A.M. is measuring the relative Olympic media buzz around the London 2012 Olympic and Paralympic Games partners, week by week. The leaderboard, right, reflects their ranking over the past week, in this case from Wednesday 4 July to Wednesday 11 July.

Samsung has been picking up coverage for its Galaxy S3 smartphone promotion. This is partly because David Beckham appears in the campaign, but also due to the launch of its London 2012 Olympic app. Otherwise, Samsung has been running a series of “Take Part” events across the country, aimed at reaching 1m people. The events are linked to social networks, and users are encouraged to tag themselves in crowd photos.
