Multi-channel DSPs for streaming TV advertising: what they are and who they suit

QUICK ANSWER

A multi-channel DSP buys streaming TV through the same account and auction tools you use for display, audio, video and other channels. It suits teams and agencies that plan CTV as one part of a wider programmatic budget.

What is a multi-channel DSP?

A demand-side platform (DSP) is software that bids for ad impressions across many publishers and exchanges. Multi-channel DSPs include connected TV as one channel among several, so frequency, audiences and reporting can be managed across channels in one place.

Who tends to choose this type?

Agencies buying for several clients, in-house programmatic teams, and brands that already run display or video programmatically and want CTV in the same seat.

What should you ask before you commit?

  • Which streaming services and networks can I reach, by name?
  • What fees apply on top of media, and are they published?
  • Is there a managed option, and what minimum does it carry?
  • Which measurement and brand-safety partners can I use?
