The main sporting events I see on TV here are Golf & Soccer (UK Premier League, European Championships, and local S league).
Once a year companies here get bombarded to entertain their corporate clients at the Malaysian F1 GP. I guess there's more, but I've not really noticed it.
Do you put adverts on sports grounds so they will be picked up by TV coverage or do you advertise sporting events?
Anyway I guess you would be approaching Event promoters, TV stations or potential sponsors on behalf of sports clubs or venues?
