Youth appeal
After watching an evening of athletics at last year's Beijing Olympics, a leading IOC member took me aside and said simply: "This sport has to change. The show isn't good enough."
Now athletics is taking the first steps to making its programme more accessible to younger people. It has to. TV audiences for its World Championships have fallen dramatically since 2000.
In an interview with BBC London, Seb Coe says the programme has to be shorter with more finals together. He also wants more commentary available to spectators.

I'm BBC London's Olympics Correspondent, which means I report on every aspect of the preparations for 2012. I'm going to be telling you what people are saying about London's preparations - both in the Olympic corridors of power and on the streets of the capital - and I want to hear your views.
