Swiss AdTech Publica4 Debuts Full-Screen 'Welcome Ad Split' Format
Zurich-based AdTech company Publica4 has launched a new advertising format called 'Welcome Ad Split'. The format initially occupies the full screen on page load before transitioning into a persistent sidebar next to editorial content. According to the company, it was played out for the first time in Switzerland on 20min.ch, with Range Rover and Defender as the launch advertisers. Publica4 handled production, adaptation, and technical delivery. The campaign achieved an average video completion rate of 68.2% for the 30-second desktop video, a click-through rate of 5.63%, and viewability of up to 92.7%. CEO Dario Piccinno argues the results challenge the industry's focus on cost-per-mille (CPM), emphasizing that the quality of attention justifies higher contact costs. The format is reportedly bookable now across major Swiss media houses in the German, French, and Italian-speaking regions.
Innovative ad format launch in Switzerland, but limited market impact.

OpenAI developing image, video and conversational ad formats
OpenAI is expanding beyond its initial single ad unit by hiring engineers to build multiple ad formats, including text, image, video, native, conversational and interactive ads. Three ad-format engineering roles posted on OpenAI’s careers page — a senior “foundational” role (7+ years) plus iOS and Android-focused roles (4+ years) — sit inside its monetization team and emphasize building infrastructure, tooling, rendering and delivery across surfaces. All roles require embedding privacy, safety, fairness and policy compliance into ad systems. The positions are San Francisco–based with compensation of $230,000–$385,000 plus equity. Industry sources note the technical and trust challenges of advertising inside advice/chat systems and say creative-format testing is overdue.
