About this site

This site explains out-of-home advertising from the perspective of inventory that moves. It is written by Ercan Bozkurt and Melih Koray, two named people rather than a media company, and published and edited by Melih Koray. It is written for advertisers and media buyers, and it publishes no operator's rate card.

Who publishes it

Melih Koray publishes and edits this site. He is a marketing and SEO practitioner who documents out-of-home media, and every page carries his name as reviewer. There are no invented author personas on this site and no fictional research body behind any figure.

Who writes it

Ercan Bozkurt writes the methodology and market pages: what a format is, how its impressions are counted, how a brand lift or incrementality study is built, what each transit authority's rulebook allows, and the city-by-city market desks. He writes the methodology pages on this site: how out-of-home inventory is counted, measured and bought, with a particular interest in screens that move. He works from the primary document in each case, the transit authority's own rulebook, the measurement body's own definitions, the company's own filing, and writes the page so that a media planner can check every figure against it.

Melih Koray writes the vendor and ranking pages, where the question is who owns what and what each seller publishes: the DOOH companies and outdoor advertising companies lists, the digital billboard page and the Chicago, Los Angeles and Miami desks. The byline at the top of every article names who wrote it; the schema names the same person.

Published and edited by Melih Koray. Disclosure: the editor is employed by Firefly, which sells moving-screen and taxi-top media and is ranked in some vendor tables on this site. Archive photographs are from Firefly campaigns. Every link to Firefly is tagged sponsored, and enquiries may be forwarded to the company. Firefly's own rates are never quoted here.

That relationship is a commercial interest, and stating it up front is the point of this section: you should know who is telling you things, and who stands to gain, before you decide what to do with them.

Who it is for

Advertisers, brand marketers, media planners and agencies: people deciding where a budget should go.

It is not for drivers looking to earn money from their vehicle. That is a common reason people arrive at a page with "car advertising" in the domain, so it is worth being blunt: there is nothing here about driver sign-up, driver pay, or how much you can make with a wrapped car. No page on this site covers it.

How figures are sourced

• Every statistic carries a named source and a date. If a figure cannot be traced to a publisher, it does not get published. Where the industry has no reliable number, the page says so rather than estimating one. Sources are listed at the foot of each article with the date they were read, and the figures the site relies on most are collected, with their bases, on out-of-home advertising statistics.
• Operator case studies are cited, not adopted. Where a measured result was published by a media operator, the page says which operator published it and who measured it, and treats it as that operator's claim rather than an industry benchmark.
• Photographs, not renders. Every image of a campaign on this site is a photograph of a placement that ran. The industry norm is composites and mockups; this is a deliberate departure from it.
• Corrections are made in place. Pages carry a published date and a last-reviewed date, and are updated when something is found to be wrong.

What it refuses to publish

• Unsourced numbers. No impression count, CPM, lift figure or market size appears without a publisher and a date attached to it.
• Any operator's rate card. This site attributes no rate, CPM or minimum budget to any operator, including the one whose campaigns the archive documents, which prices per campaign and publishes no rate card. Where cost is unavoidable as a topic, it is described structurally, from third-party published ranges, and those ranges are not quotes.
• Driver and vehicle-owner earnings programmes. Nothing on this site covers that side.
• "Best of" lists and thin city pages. Where this site orders vendors, on DOOH companies, the criteria are stated and every line is read from the company's own page. Market desks such as Chicago share one structure, and each is published only when the archive documents campaigns there and the authority's own standards and named rate publishers were read live.

Where the photographs come from

The campaign archive holds 3,783 photographs of out-of-home placements covering 603 brands across 21 US markets between 2020 and 2026. They come from the proof-of-performance archive of one out-of-home operator, the operator referred to in the disclosure above, and are used with that operator's permission.

Every frame was looked at by the editor and classified by ad surface, carrier vehicle and deployment pattern, which is the classification the guide to out-of-home advertising and the examples page are built on. Captions state only what the record shows: brand, city, format and year. They are published as evidence of what formats look like in the field and of where formats have actually run. They are not an inventory list, not an availability claim and not an offer. 459 frames have a source date that does not parse cleanly and are shown without a year rather than with a guessed one.
