At WOO’s London 2026 Annual Congress, the “Regulation and Reputation (Perception is Reality)” session put one of the Out of Home industry’s most urgent questions at the centre of the agenda: how does the medium protect public trust before isolated restrictions become a wider pattern of regulation?

Moderator Kai-Marcus Thaesler, CEO of the German Outdoor Advertising Association, opened by introducing WOO’s new regulation initiative as a global response to what he described through the image of a domino effect. The point was deliberately simple: when one market faces a restriction — whether on digital screens, motion, light, product categories or public-space aesthetics — the argument can travel quickly. A local decision can become a regional precedent, and a regional precedent can harden into a global perception of the medium.

Thaesler set out the scale of the issue with a worldwide map of OOH and DOOH restrictions. The presentation grouped restrictions around several recurring pressure points: health and HFSS rules, tobacco and alcohol limits, fossil fuel and climate-related bans, DOOH motion restrictions, light pollution concerns and broader political or aesthetic interventions. The map made clear that this is no longer a single-market or single-category question — regulation is coming from national governments, city authorities, transport bodies and citizen initiatives.

That framing led into a discussion with Bongumusa Makhathini, CEO of Primedia Out of Home in South Africa, and Guy Parker, Chief Executive of the UK Advertising Standards Authority. The conversation repeatedly returned to the title’s central proposition: perception is reality. The industry may be legally compliant, but if communities, regulators or policymakers perceive the medium as intrusive, unsafe, irresponsible or poorly governed, that perception can become the basis for restriction.

Parker’s contribution brought the self-regulatory perspective into focus. The message for OOH was that reputation is not defended only when a crisis appears — it is built through clear standards, visible accountability and a willingness to deal with problematic advertising before it damages confidence in the whole channel.

Makhathini added the market-operator perspective, underlining that trust is earned locally. Public acceptance depends not only on commercial performance but on whether the industry is seen as constructive, responsible and responsive to the places in which it operates.

Thaesler then positioned WOO’s role as a coordinating force rather than a central regulator — helping members move from reactive defence to evidence-led preparation through four overlapping workstreams.

WOO’s coordinating role

1. 01

   Knowledge Transfer

   Sharing methodology, evidence and regulatory responses across markets, so that lessons learned in one country reach others before similar restrictions are proposed elsewhere.

2. 02

   Early Warning

   Surfacing emerging regulatory developments at national, city and transport-body level, giving members time to prepare evidence-led responses rather than react to a final decision.

3. 03

   Best-Practice Hub

   Documenting the standards, self-regulatory frameworks and accountability mechanisms that have helped specific markets retain public trust under pressure.

4. 04

   Roundtables & Expert Network

   Convening international roundtables and a network of strategists, researchers and lawyers, so members can draw on shared expertise rather than commissioning it locally from scratch.

The session ended with a clear call for coordination. OOH’s growth will depend not only on creativity, technology and audience value, but on the industry’s ability to maintain legitimacy in public space — and on its willingness to act early, before isolated restrictions tip into a wider pattern.

In regulation, reputation is not a soft issue. It is operational protection.
