Advertising network
company that connects advertisers to websites that want to host advertisements
An advertising network or ad network is a business that links advertisers with websites or apps that want to show ads. Its primary purpose is to match advertisers with ad publishers to fill ad space.
Ad networks have expanded from primarily TV and print advertising to online advertising. Online networks use a central ad server to send, follow, and measure ads in real time. Compared to older, non-digital media, this allows companies to better target audiences, track performance, and get more detailed reports.
Overview
The global advertising network market is large and continues to grow. According to WARC's Q3 2025 forecast, global advertising spending was projected to grow 7.4 percent in 2025 to reach US$1.17 trillion, with digital-first platforms capturing approximately nine out of every ten incremental ad dollars.
Online advertising inventory exists in a wide variety of formats, including placements on desktop and mobile websites, RSS feeds, newsletters, blogs, instant messaging applications, mobile apps, email, and other digital media. The most prominent sources of inventory include third-party content websites that collaborate with advertising networks in exchange for revenue sharing or service fees, as well as search engines, mobile platforms, and online video services.
Advertisers may purchase either a run-of-network package or a category-specific package within an advertising network.
This brief starts where responsible research should: with the source description of “Advertising network” as company that connects advertisers to websites that want to host advertisements. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as company that connects advertisers to websites that want to host advertisements. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q2914704. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2025.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
