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 24 May to Wednesday 7 June.

Omega, the official timekeeper of London 2012, aired its TV advert on YouTube last week. It was well received, with over 55,000 views since its launch and a positive response on social media channels. Using the Rolling Stones track Start Me Up as its inspiration, the firm is encouraging Twitter users to use the hashtag #startmeup. This was initially successful, but interest has steadily dropped off. While rarely in the top five of our rankings, Omega performs well considering the size of the companies it is competing against.
