VIOOH announced a partnership with Grupo IMU on July 16, 2026, opening more than 400 digital screens across six Mexican cities to programmatic buyers. The agreement connects one of Mexico's longest-established outdoor media companies to a supply-side platform trading in 37 markets, and it extends a Latin American expansion that has already brought Colombian and Brazilian inventory into automated reach.

The announcement, issued from London on Thursday, July 16, 2026, frames the arrangement as a route for international media buyers into Mexican audiences. According to VIOOH, the partnership delivers access to more than 400 digital screens generating millions of monthly impressions. Grupo IMU's network covers airports, bus shelters, outdoor billboards and urban panels positioned around shopping centres, gyms, salons and residential properties.

What the agreement covers

Geographic coverage concentrates on six cities plus one transport hub. According to the announcement, Grupo IMU maintains placements across Mexico City, the State of Mexico, Puebla, Guadalajara, Monterrey and Mérida, alongside Mexico City International Airport. VIOOH states that the footprint allows advertisers to connect with consumers throughout their daily journeys at national scale.

The environments involved carry different exposure characteristics. Airport placements reach travellers during extended dwell periods. Bus shelters deliver street-level frequency to commuters. Panels positioned near shopping centres, gyms, salons and residential buildings generate repeat exposure among local audiences moving through routine locations. That mix distinguishes the network from portfolios built around a single format, such as roadside billboards alone.

Transactions will flow through VIOOH's supply-side platform, the technology layer sitting between media owners and the demand-side platforms through which advertisers execute automated buys. Buyers already connected to one of VIOOH's DSP partners can access Grupo IMU's enabled inventory without establishing a separate direct sales relationship with the Mexican company. Standard programmatic digital out-of-home protocols apply: advertisers bid on available impressions, with targeting parameters typically spanning environment type, geography, time of day and audience data integrations. According to VIOOH, programmatic buying through its platform gives advertisers enhanced flexibility, precision targeting and improved efficiency across Grupo IMU's network.

Several details remain undisclosed. The announcement does not state financial terms, whether the arrangement is exclusive, what share of Grupo IMU's total inventory the 400 screens represent, or when individual demand-side platforms will begin transacting on the supply. Nor does it break the screen total down by city or environment, leaving the airport share of the count unquantified.

How the two companies frame the deal

"This partnership with Grupo IMU marks an important step in VIOOH's expansion across Latin America, connecting media buyers with high-quality, flexible and brand safe inventory in one of the region's largest and fastest-growing DOOH markets," said Gavin Wilson, Global Chief Commercial Officer at VIOOH. "Mexico is a market full of potential for pDOOH, and Grupo IMU's inventory puts brands right at the centre of it; from major metropolitan hubs to regional audiences that are harder to reach through other media channels."

The Mexican company emphasized the demand side of the equation. "Integrating with VIOOH's global supply-side platform gives our inventory unique reach among international media buyers seeking to connect with Mexican audiences," said Angel Romo, Marketing Director at Grupo IMU. "This partnership opens new doors for brands to activate campaigns across our network programmatically, with the precision and measurability that today's advertisers demand."

Both statements describe a familiar exchange in programmatic out-of-home partnerships. The media owner gains exposure to international budgets flowing through automated pipes. The platform gains inventory in a geography where it previously offered buyers little or nothing.

The platform behind the transaction

VIOOH launched in 2018 with headquarters in London, backed at the outset by JCDecaux, which held a 93.5 percent ownership stake. According to VIOOH, the platform currently trades programmatically in 37 markets and drives demand through partnerships with more than 50 demand-side platforms globally, with more to follow. That market count has climbed steadily: the company cited 35 markets in late 2025 and reached 37 by March 2026, a figure it repeated when Canada's largest digital out-of-home network joined the platform in May 2026.

The Mexican agreement lands within an unusually dense sequence of supply integrations. January 2026 alone brought more than 5,000 US grocery and transit screens through Dolphin OOH and 784 displays across German Shell station forecourts through ISM. In March 2026, VIOOH and OUTFRONT connected more than 7,600 US screens and 18 billion monthly impressions, placing roughly a quarter of the American digital out-of-home market within programmatic reach. April 2026 brought 60,000 moving vehicle-top and rideshare screens through Firefly. June 2026 saw UK motorway service area inventory arrive through i-media. Each deal has added a categorically different environment to the same aggregation layer, from grocery stores and gas stations to residential lobbies and now Mexican airports.

Grupo IMU's position in Mexican outdoor media

According to Grupo IMU, the company has operated for more than 25 years and maintains an ecosystem of formats located at key mobility and high-value advertising points. The company describes an approach combining data, geomarketing, coverage, creativity and digital formats to build campaigns connected to audience movement patterns across Mexican cities. Its portfolio spans both traditional out-of-home and digital out-of-home formats.

For a media owner of that profile, programmatic enablement changes the addressable customer base. Direct sales operations reach agencies and brands with existing Mexican relationships. A supply-side platform integration exposes the same screens to any buyer holding a seat on one of more than 50 connected demand-side platforms, many of them planning campaigns from London, New York or São Paulo rather than Mexico City.

The Latin American sequence

The Grupo IMU agreement is the third media-owner partnership VIOOH has announced in Latin America since October 2025. The sequence began when iCo Medios brought 72 screens across Bogotá, Medellín and Cali into programmatic reach, a Colombian network generating over 32 million monthly impressions. One month later, RZK Digital added more than 800 screens across 43 Brazilian bus terminals. Mexico now joins as the region's second-largest economy, filling the geographic gap between VIOOH's North American buildout and its South American entries.

The regional market carries meaningful scale. The Latin American out-of-home market reached 2.7 billion dollars in 2024, based on World Out of Home Organization figures, with Brazil accounting for over one-third of the total and 31 percent of regional out-of-home advertising already delivered through digital formats. Capital has followed the audience. MiQ acquired Adsmovil's Latin American business in March 2026, part of a broader thickening of programmatic infrastructure across the region spanning digital out-of-home, connected television and retail media.

Two technical routes have opened the region's screens to automated buying. Demand-side platforms have built supply directly: Vistar Media's August 2025 Brazil launch connected more than 30,000 screens to its own buying interface. VIOOH works from the opposite end of the transaction, integrating individual media owners into a supply layer reachable from any connected demand-side platform. The Grupo IMU agreement follows the second model, meaning access arrives through tools buyers already operate rather than through adoption of a new one.

Why the deal matters for media buyers

The practical consequence sits in campaign planning workflows. A buyer assembling a multi-country Latin American campaign can now reach Colombian, Brazilian and Mexican out-of-home audiences through a single supply-side connection, using the same demand-side platform seat, targeting logic and reporting framework applied to inventory in the United States, Canada, the United Kingdom or Germany. Before integrations of this kind, each national out-of-home buy required separate negotiation with local media owners, separate insertion orders and separate measurement arrangements.

Scale expectations deserve calibration. The millions of monthly impressions described in the announcement place the Mexican network well below VIOOH's largest integrations; the OUTFRONT arrangement alone delivers 18 billion monthly impressions. The value of the Grupo IMU deal rests on geographic and environmental coverage rather than raw volume. Advertisers seeking Mexican audiences through automated channels previously had fewer paths into premium street furniture, airport and billboard inventory in the country.

Demand-side appetite appears to be moving in the same direction. VIOOH's 2026 State of the Nation report forecast programmatic digital out-of-home appearing in 48 percent of all campaigns globally within 18 months, up from 34 percent over the preceding period, with average investment expected to rise 44 percent. If those projections hold, supply platforms with broad national coverage stand to capture a growing share of budgets that once flowed through direct sales channels.

Measurement frameworks travel with the platform. VIOOH reported an emissions intensity of 0.041 grams of CO2 equivalent per ad impression for full-year 2024, a figure the company contrasts with display advertising benchmarks and its third consecutive year below industry standards. Screens joining the platform, including Grupo IMU's, fall under the same viewability and emissions accounting applied across the other markets.

For Mexican advertising professionals, the integration works in the opposite direction. Local inventory becomes visible to international demand, which can lift yield on screens that domestic direct sales alone might not fill. Whether that international demand materializes at meaningful volume in Mexico remains the open question the coming quarters will answer.
