A method of facilitating placement of an advertisement. A specification, which includes at least a budget and a reserve cost and designates creative material for the advertisement, is received from an advertiser. A deposit of funds, in an amount that is at least equal to the budget, and the creative material, are also received from the advertiser. The specification is publicized to media carriers. One or more bids from one or more of the media carriers are received. Each received bid is compared with the specification. Those media carriers submitting bids which are below the reserve costs are identified. The creative material is then transferred to each of the identified media carriers for placement.
