Have a look at this website I have just found www.RotateAd.com. This is a new Rotate Ad site that has one large advert on the main page. The site has six hours of advertising for sale split into seconds. Advertisers can buy seconds to have their advert placed on the main page. The site will rotate between which ever adverts are currently placed 24 hours a day. It is a new twist on current internet advertising. I think this will be the next big thing in internet advertising!
