Download websites that use Media.net

An advertising tag is one of the few things a website publishes about its own business model. Media.net is a sell side advertising platform, which means it fills the ad slots on a publisher's pages and sells that space to advertisers on the publisher's behalf. A publisher who installs the tag has already made a decision worth recording: the site carries paid inventory, the owner will trade screen space for revenue, and there is a payout attached to the traffic.

Our vendor column records Media.net, but the network's own account of its history names a different founder and a later change of ownership, so that field is worth treating with caution. The service dates to 2010 in our records and remains a Proprietary hosted product. Integration is a JavaScript snippet dropped into the page template, which is the reason detection is possible at all. There is no server software to fingerprint and no response header to read, so the question is simply whether the loader appears in the markup. Compared with Advertising systems that run entirely server side, that makes presence a clean binary signal rather than an inference from side effects.

As of October 2026 we see the Media.net loader on 2,255 sites. The count should be read as sites carrying the code, not sites earning money from it. A tag can sit in a template long after the publisher stopped caring, inventory can go unfilled, and a network loaded through a header bidding wrapper or a tag manager can be invisible to a crawler that only reads delivered HTML. Undercounting is the more likely error of the two, and buyers who need a floor rather than a census should treat the number that way.

The people who ask for this list are usually on one side or the other of publisher monetization. Rival networks and monetization consultants use it to find sites that already accept third party ad code, which removes the hardest objection from a sales conversation. Header bidding and yield vendors use it to find publishers with an existing revenue baseline to beat. Brand safety teams use it in the opposite direction, checking which advertiser funded pages sit next to content they would rather not appear beside. Researchers studying how the open web pays for itself use it to measure how far paid inventory reaches across content categories.

None of that is answerable by looking up one domain at a time. A per-domain lookup tells you whether a single publisher runs Media.net, which you usually already suspect. A downloadable list tells you how many publishers there are, which countries and top level domains they cluster in, which content management systems they run underneath, and how the population moves as networks win and lose publishers. Sizing a market, building an outreach territory, or tracking a competitor's publisher base all need the whole population in one file, joined to the other columns rather than collected by hand.
