A media planner is launching a brand campaign and requires a committed volume reservation within a specific, curated list of premium digital radio stations. Which inventory source allows the publisher to reserve this capacity at a pre-negotiated rate?

Programmatic Guaranteed is the reservation model in Display & Video 360 for inventory that is agreed upon between buyer and seller up front, with settings such as price fixed in advance. Google describes it as a direct buy with publishers and documents that guaranteed deals are negotiated before delivery rather than won through auction competition. That structure supports a committed volume of reserved inventory at a pre-negotiated CPM, which is exactly what a curated premium digital radio buy requires. It is the only option here built for reserved capacity instead of auction access or bid optimization. support.google.com+1
