List of online advertising DSPs from around the Web. The term DSP means "demand-side platform." This refers to a service that handles bids and purchasing for online ads on behalf of another company, typically in an auction-based system. (In other words, the DSP is bidding for online ad space on behalf of an advertiser or marketer.) The DSP thus is an impartial third-party service that can work with a variety of companies and clients on one side, and with a variety of ad networks and publishers on the other side. Several companies, including Yahoo and Google, operate their own DSPs, while some DSPs operate independently.What are the best DSP companies?
