Open Ad Exchange (aka open marketplace, open auction)

An open ad exchange (also known as open marketplace) is an ad buying and selling environment in which the media allows buyers to access their inventory. Media owners choose to participate in these platform to gain access to new customers or sell unsold inventory (also known as remnant space or inventory). Fliphound is a pioneer in automating ad buying and selling for digital billboards and works with billboard companies and networks to help them enable online selling and access internet advertisers. With Fliphound, unlike many of the internet ad exchanges the media and billboard owners maintain rights to accept and approve advertisers and content that is displayed on their out-of-home networks.
