Supporting our regular Campaigns Of The Month series, this is the first in a new regular feature putting a spotlight on case studies across our member network, verified against a clear set of standards.</p> <p>This edition: Trunk, for their World Cup 2026 campaign with Greene King.</p> <h2>The Challenge</h2> <p>Greene King Sport needed to become the destination of choice for football fans across the UK during the 2026 World Cup, against a crowded pub and restaurant sector, a time-poor audience, and a fixture schedule complicated by North American time zones.</p> <h2>The Work</h2> <p>Trunk built a nostalgia-led creative platform, "The World's Game, The Nation's Pub," reminding audiences Greene King had been part of every major football moment and inviting them back for the next one. Cast members representing key World Cup nations wore wardrobe evoking national kits, shot with an editorial photography approach inside a real Greene King Sport pub. Two hero executions, for England and Scotland, ran across TV, print, OOH, digital and video.</p> <figure class="gn-fig gn-reveal"> <div class="gn-fig__media"> <img src="https://cdn.prod.website-files.com/6877701b88030d58f11ac053/6abe2fb2c915c528f0f02223_Trunk%202.avif" alt="Trunk's World Cup 2026 campaign for Greene King" style="width:100%;height:auto;border-radius:8px;"> </div> </figure> <h2>The Results</h2> <ul> <li>Double-digit millions in year-on-year sales growth</li> <li>A significant increase in bookings compared to the previous tournament</li> <li>A meaningful lift in loyalty app engagement during the tournament</li> <li>A strong competitive position held for the full duration</li> </ul> <figure class="gn-fig gn-reveal"> <div class="gn-fig__media"> <img src="https://cdn.prod.website-files.com/6877701b88030d58f11ac053/6abe2fb2eec4a7a45c956a6c_Trunk%203.avif" alt="Trunk's World Cup 2026 campaign for Greene King" style="width:100%;height:auto;border-radius:8px;"> </div> </figure> <h2>Why This Case Study Stands Out</h2> <p>Beyond the creative, this is a genuine best-practice example: a clearly explained strategic rationale, specific production decisions, sector context that makes sense to anyone outside pubs and hospitality, and results benchmarked against a real prior comparison rather than stated in isolation. That combination, strategic thinking plus commercial proof, is what we look for when we feature work from our network.</p> <figure class="gn-fig gn-reveal"> <div class="gn-fig__media"> <img src="https://cdn.prod.website-files.com/6877701b88030d58f11ac053/6abe2faf7dc6cb9b526fb8ab_Trunk%204.avif" alt="Trunk's World Cup 2026 campaign for Greene King" style="width:100%;height:auto;border-radius:8px;"> </div> <figcaption>All credit goes to Trunk &amp; Greene King</figcaption> </figure> <div class="gn-reveal" style="background:#2563eb; border-radius:12px; padding:20px 28px; margin:34px 0; text-align:center;"> <p style="margin:0; font-size:15px; color:#ffffff;">Keen to explore work and case studies that might fit your challenges and ambitions? <a href="https://www.thegonetwork.com/book-a-call?tab=1" style="color:#ffffff; font-weight:700; text-decoration:underline;">Talk to us about your brief</a></p> </div> <div class="gn-reveal" style="background:#f97316; border-radius:12px; padding:20px 28px; margin:34px 0; text-align:center;"> <p style="margin:0; font-size:15px; color:#ffffff;">Is your agency producing exceptional work and results? <a href="https://www.thegonetwork.com/download-intro-to-membership" style="color:#ffffff; font-weight:700; text-decoration:underline;">Explore membership</a></p> </div> </div></div>
