The client of an outdoor advertising company could either be an advertising agency or a manufacturing company or marketing company as the case may be. The client rents a billboard from the outdoor advertising company for a specific period of time, usually one year. This rental contract is normally renewed at expiration. Rental rates for conventional outdoor advertising billboards such as 40 sheet, 16 sheet, bulletin boards, street directional signs and 4 sheet are usually determined and regulated by the Outdoor Advertising Association of Nigeria (OAAN).
The rental rates for unique billboards designed and introduced by an individual company within the association are usually determined by the company that introduces such unique boards e.g. – Optimum Exposures introduced the “Spectaculars” and the rental rates are determined by Optimum Exposures only.
