It is commonly known that programmatic inventory provides significant scale and efficiency when it comes to targeting audiences across devices and formats, but this needs to be planned carefully. In recent years, the programmatic inventory landscape has rapidly evolved, with more publishers leading a ‘programmatic-first’ mentality and, as a result, a wider array of formats becoming available programmatically across all devices.

James Diba, client partner at The Programmatic Advisory, shares some key findings from the analysis published in the consultancy’s recent whitepaper.
