How CS Hammam-Lif Turned Silent Stadiums Into Roaring Arenas
Mobilizing The 12th Man is a 2013 mobile-led campaign created for CS Hammam-Lif by Memac Ogilvy Label Tunisia that connected remote supporters to 40 giant speakers placed inside a stadium during a professional football match played without a live audience in Tunisia, allowing fans to generate real crowd noise through a downloadable app while watching the game on television.
The Tunisian Government had imposed a ban on spectators at all Professional Football League matches for security reasons, leaving clubs to compete in eerily empty stadiums. For CS Hammam-Lif, a historical Tunisian football club, the timing could not have been more critical. With the most important fixture of the season approaching and average results casting doubt over the club's standing, the absence of crowd support threatened to strip the team of its most powerful motivating force. The campaign was conceived in direct response to that institutional silence.
The mechanics were deliberately simple. Supporters downloaded The 12th Man app onto their mobile devices. During the live match, every tap on the app's sound icons — cheering, clapping, drumming, singing — was transmitted in real time to 40 speakers distributed throughout the stadium. The collective intensity of fan interaction determined the volume: the more supporters pressed, the louder the stadium roared. In the Tunisian market, where football culture carries deep community significance, the app functioned as a civic act as much as a sporting one.
The campaign launched in July 2013 and was produced by Memac Ogilvy Label, operating under the OgilvyAction Tunisia network. It earned a Clapboard Score of 82 out of 100, reflecting its structural originality and measurable cultural impact. The work went on to accumulate one of the most decorated award tallies in Tunisian advertising history, cementing its place as a landmark in mobile and experiential creativity across the region.
CS Hammam-Lif faced a constraint that no conventional marketing solution could resolve. The Tunisian Government's decision to close stadium gates to spectators was absolute, leaving clubs without the atmospheric advantage that home support typically provides. The strategic insight driving Mobilizing The 12th Man was precise: the ban prohibited physical presence, not emotional participation. If the fans could not enter the stadium, the stadium could be brought to the fans — and their collective voice could be carried back inside.
This insight required a platform capable of aggregating thousands of simultaneous individual actions into a single coherent output. The mobile app served that function, acting as a conductor between dispersed supporters and centralised speaker hardware. The strategic elegance lay in converting passive television viewing, an activity fans were already engaged in, into an active, consequential form of support. Every tap had a measurable effect on what players heard on the pitch.
The broader context reinforced the campaign's ambition. Football was, by 2013, a sport generating revenues of significant scale globally, though the specific dynamics of Tunisian club football are shaped by factors particular to the North African market, including fan loyalty structures, limited digital infrastructure relative to European leagues, and the acute sensitivity of live-match atmosphere to audience presence. In that environment, a campaign that restored crowd noise through technology addressed a genuinely felt absence rather than a manufactured problem.
The competitive landscape for Tunisian clubs seeking fan engagement solutions in 2013 had no direct precedent for this approach. No named competing brand or rival campaign appears in the available record. The campaign therefore operated as a category-defining act, establishing a new model for technology-mediated fan participation in markets where physical access to sporting events is restricted by governmental or logistical constraints.
The creative execution of Mobilizing The 12th Man rests on a single, legible interface decision. The app presented users with a set of sound icons representing the repertoire of stadium support: cheering, clapping, drumming, singing, and goal celebrations. A tap on any icon triggered an immediate audio response inside the stadium through the network of 40 speakers. The interaction was designed to feel instinctive, requiring no instruction beyond the natural impulse of a fan reacting to the game unfolding on their television screen.
On screen, the campaign's documentary material captures the contrast between silent stands and the growing acoustic presence generated by the app. Empty terraces are shown alongside the speakers positioned throughout the stadium, while audio builds as participation increases — a visual and sonic demonstration of the technology's effect in real conditions. The footage records the moment the concept becomes tangible: a stadium without people that nonetheless sounds inhabited.
The team at Memac Ogilvy Label Tunisia assembled a substantial creative unit for the project. Executive creative director Nicolas Courant led the work, with conceptualizer Mehdi Lamloum shaping the core idea and copywriter Sascha Kuntze responsible for the campaign's written voice. Art direction was handled by Gerald Heraud, Leo Ehrlich, Alexandre Chaulet, Niv Banhiamad, Yosri Mimouna, and Ali Bhiri. Managing director Syrine Cherif and business director Mouna Ben Hammouda oversaw the agency relationship, while producers Bedis Benamor, Ali Abdennadher, and Zied Ben Ziaoui managed delivery. Project management was led by Ghazi Triki. The scale of the production team reflects the technical and logistical complexity of installing and operating 40 speakers within a live stadium environment under real match conditions.
Mobilizing The 12th Man produced results that were both quantifiable and historically significant for Tunisian advertising. According to chrisrawlinson.com, approximately 93,000 fans participated in the campaign — nearly eight times the stadium's physical capacity of 12,000. The match ended in a 1–0 victory for CS Hammam-Lif, a result that, per chrisrawlinson.com, helped the club avoid relegation. The campaign therefore achieved its primary objective: restoring competitive crowd support under conditions designed to eliminate it.
The awards record is extensive and independently verifiable. At the 2013 Cannes Lions, the campaign received five Silver Lions across the Outdoor, Media Use of Audio, Mobile, Mobile Integrated Led by Mobile, and Promo and Activation categories, plus one Bronze Lion in Branded Content and Entertainment, as reported by selfstorming.com and adbasha.com. At the 2014 Clio Awards, the work earned Gold in Digital and Social, Silver in Events, and Bronze across Events and Experiential, Apps, and Other categories, according to clios.com. The London International Awards 2013 recognised the campaign with a Silver in Non-Traditional Interactive Installations and Bronze awards in Non-Traditional Live Events and Non-Traditional Sports, as documented by liaawards.com.
No single prior Tunisian campaign appears in the available record as having accumulated a comparable concentration of international recognition across mobile, experiential, and outdoor categories simultaneously. The Clapboard Score of 82 out of 100 reflects the campaign's structural originality, its measurable real-world outcome, and the coherence between its creative mechanism and its stated objective.
