When you go back to the above names it was a very much narrower situation - the alternatives were far fewer. Today there is much more competition for the 'hero stakes'! And if you think about all the alternatives you have today to spend your time on, the pool of heroes is much broader. It was very much less back then.

There is much romanticism about Formula One of the past. Today it has to be more of a family sport, not less. It is a fixture in the Sunday afternoon TV programmes, and probably flamboyance - those white silk suits and devil-may-care attitudes - would be outworn attributes today.

You could think about Vietnam and at some point in time about Nigeria. And then you head to South America: Argentina, Columbia, Peru. Probably not all of them will have an F1 race, but they are definitely considering events.

And there are some - Bernie [Ecclestone] and others - who are embracing new technologies. When Sky UK started to broadcast there was an argument that audience would come down because it is pay TV.
