Literally – outside of the four walls of consumers’ residences to capture their attention with out-of-home (OOH) marketing.  

 At the beginning of 2024, the global ad spend on the OOH advertising market is projected to reach nearly $30 billion

Why are Out-of-Home Marketing Campaigns Valuable? 

Brands leveraging this powerful strategy effectively can reach new personas, improve brand awareness, drive sales, and foster deeper connections with their target audience.  

The average consumer spends 70% of their time awake outside of their home. It is also reported that 9 out of 10 adults notice an OOH advert and out of those viewers, 80% are inspired to take action and make a purchase. 

Studies have shown OOH delivers 4x more online activity per ad dollar spent. In a digital world full of ads, consumers are used to scrolling past, skipping, or even blocking online advertising. This is why OOH complements digital channels, as consumers cannot avoid in-person marketing campaigns as easily and in tandem drives online activity.  

Some of the best out-of-home advertising can be transformed into a social media frenzy as 1 in 7 viewers are likely to take a picture of an OOH advert and share it online. Here are a few out-of-home advertising examples that went viral: 

Netflix’s New Show, Resident Evil, was presented on a Times Square animated 3D billboard with a frog that breaks through a glass box. Several social media accounts that shared the lively billboard had nearly 950,000 views. 

Pepsi Max’s Unbelievable Bus Shelter received 3 million views in 5 days and more than 8 million views total from the virtual reality bus stop that surprised many of its occupants with realistic effects.   

The History of Out-of-Home Marketing Campaigns 

 Out-of-home campaigns are not a new concept though – OOH was around long before social media and digital advertising even existed.   

 So, let’s throw it back – to the early 1800s when the first series of billboards were created by paint or by gluing a poster to a wall, and the primary industry using this form of advertising was entertainment, specifically the “greatest show on earth” – the Ringling Brothers circus.  

 Fast forward to the 1900s, when many iconic billboards emerged dotting landscapes across the nation and capturing imaginations with campaigns from industry giants like Coca-Cola.

Transition to Digital 

 From brick to click, as the years went on there was a seismic shift – the rise of digital screens. 

 Traditional billboards were transformed into vibrant canvases capable of dynamic content, real-time updates, and targeted messaging. 

Key milestones in OOH's digital transformation include: 

1910s: Times Square lights up with its first electric billboard, ushering in an era of dynamic displays. 

1940s: Neon signs become a fixture, adding a vibrant glow to cityscapes. 

1970s: Mobile billboards and transit advertising expanded their reach beyond static structures. 

 In today’s digital age of AI, advertising is continuing to evolve with innovative ways for brands to create and deliver campaigns.  

Digitization is revolutionizing OOH advert strategies: 

Hyper-targeting: Digital OOH allows advertisers to pinpoint specific demographics and interests, delivering relevant messages based on location, weather, and even current events. 

Enhanced engagement: Interactive screens foster two-way communication, inviting consumers to scan QR codes, play games, or participate in polls. 

Data-driven optimization: Real-time tracking and analytics provide valuable insights into campaign performance, enabling continuous optimization and adjustments. 

 AI creates personalized and engaging advertising experiences to make lasting impressions with consumers, improving the effectiveness of the OOH campaign. Whether it is an AI campaign that uses a digital billboard to advertise a thirst-quenching beverage on a scorching day or AI video editing of world-recognized soccer player, David Beckham, and translating it flawlessly into 9 different languages – AI is enhancing the way OOH is capturing and maintaining the audience’s attention. 

What is OOH TV Advertising? 

OOH TV advertising takes digital screens to the next level, transforming public spaces into mini theaters. CPG brands can leverage captivating video content to tell their stories, showcase products, and attract viewers in immersive experiences. 

 For example, Coca-Cola's "Share a Coke" campaign transformed bus stops into miniature cinemas, featuring personalized greetings and stories displayed on digital screens. This interactive approach builds brand loyalty and emotional connections with consumers. 

Best Practices in OOH Advertising for CPG Brands 

 To create effective OOH campaigns for brands to stand out, there is a lot more to consider than just having a great creative and well-thought-out copy. Here are some key strategies:  

  • Location is key: Choose high-traffic areas frequented by your target audience, think grocery stores, bus stops, and commute routes. Billboards in areas with a lot of road traffic where people can be stuck for a while or bus stops that are heavily frequented are strategic placements for OOH campaigns.

  • Simplicity reigns: Keep messaging concise and impactful. Remember, you have fleeting moments to grab viewers’ attention and allow them to absorb information. 

  • Cohesive brand: Vibrant visuals and brand colors instantly grab attention to create memorability, building brand awareness and recognition.

  • Strong Call to Action: Make sure your call to action is clear and easy to read. Prompt viewers to interact, whether it's visiting a website, scanning a code, or entering a contest.

Successful Out-of-Home Marketing Campaigns 

One brand that does a particularly good job of strategizing and executing OOH campaigns is Coca-Cola. As mentioned earlier, Coca-Cola was one of the first major adopters of billboards and created many out-of-home marketing campaigns.  

 The popular beverage brand’s OOH footprint goes far beyond billboards now with plenty of successful out-of-home advertising examples including: 

Surprise Pop-Ups: Coca-Cola surprised college students at a Singapore college with a vending machine that would give a free beverage in exchange for a hug.  

Interactive Digital Displays: Coca-Cola created an advertisement that was so good you could almost drink it. The digital advertisement encouraged by-passers to use the app to fill the display bottle and in return, get a drink discount code. 

The power of speech: Using voice recognition, Coca-Cola installed a progressive display where people had to shout “yes”, and a complimentary drink would be dispensed. 


Coca-Cola isn’t the only CPG company that does best out-of-home advertising campaigns – here are some of the top brands that nailed their OOH campaign: 

Doritos’ "Raining Doritos" campaign: Digital screens on bus stops simulated falling chips, triggering playful interactions. The simulation caused a lot of social media buzz which increased brand awareness and reached new audiences, while also improving engagement through the interactive element.  

Snickers’ "You're Not You When You're Hungry" campaign: Interactive digital billboards displayed hilarious personalized messages based on facial expressions, sparking laughter and brand recall. As a play on their iconic slogan, Snickers incorporated personalization to help grab the audience’s attention while the interactive portion kept them engaged.
