Strong Reach and Brand Safety Among Highest Indicators of Quality Inventory

Brands and agencies often discuss the need to buy ‘quality inventory’, but what that inventory actually looks like can be hard to define. According to a new survey from EMARKETER and Verve, most media buyers associate the term with strong reach in the right environments (60.5 percent) and brand-safe environments (53.8 percent). But the research found less agreement around technical or operational definitions of quality inventory, with just 16 percent associating the term with inventory that performs well without relying solely on identifiers, and only 18.5 percent considering direct supply paths as a defining factor.

The combined share of US audience demand for series on channels and streaming services owned by Warner Bros. Discovery (WBD) and Paramount is set to reach 27 percent when the companies merge, according to Parrot Analytics, outgrowing Disney at 18 percent. “In terms of cultural footprint and franchise power, bringing together DC, Harry Potter, HBO’s prestige pipeline, Star Trek, and the Yellowstone universe creates an entity capable of dominating the attention economy for decades,” the analysts said in the research.
