Well this may answer one of the questions about the support of Autosport magazine. I may be putting two and two together and making five but I doubt it.
Taken from Wiki:
Haymarket Exhibitions
The company's first foray in exhibitions occurred in 1990[6] on the back of the popular Autosport weekly magazine, produced by Haymarket Consumer Media. The consumer exhibitions division is now a market leader in the UK, with an increasing portfolio and audited attendance of over half a million paid visitors.
The Exhibitions division operates in consumer and business-to-business sectors,
whilst running a successful joint venture with BBC Worldwide and various other partners.
Haymarket Exhibitions' shows are known for their quality of content and are registered with the Association of Event Organisers.[7]
Its main portfolio and diary for 2011 currently includes:
* Autosport International
* Cereals - The UK's largest exhibition by space
* BBC Gardener's World Live
* BBC Summer Good Food Show
* Fruit Focus - The Fruit Industries Premier Event
* BBC Good Food Shows[8] taking place in Birmingham, London & Scotland
* Clothes Show Live
* The Dance Show
Guess that's why there's no boat rocking against the BBC then?
