Advertising & Media Agencies companies using Quantcast: common questions

How many Advertising & Media Agencies companies use Quantcast?

100, as of 7 November 2026 — 5% of the 2,003 companies we found carrying the Quantcast tag. A company counts here when Advertising & Media Agencies is one of its sectors in our classifier, so it can also appear under other sectors. This counts companies we can tie to a company profile, so it is a floor, not a market total.

Which Advertising & Media Agencies companies advertise with Quantcast?

They include ADWEEK, Front Office Sports, Morning Brew, RRD Global Delivery Centers and First Page. The table on this page shows 20; the full list has all 100.

Where are they headquartered?

United States (60%) and United Kingdom (8.2%) lead, out of 97 companies with a known HQ.

How big are they?

3% have more than 1,000 employees; the most common size band is 11–50 employees.

How do you know a company runs Quantcast?

We find the Quantcast tag in the company's tag-manager container (attributed to the container's owner) or live on its pages, then match the domain to its company profile. A tag means measurement is set up, not that a campaign is running today. Full method on the Quantcast study page.
