Fans, Idols, and Outdoor Advertising — The Billions Behind Fan Campaigns

Every year, millions of dollars move through outdoor advertising for reasons most media buyers never consider: fans. Supporters of K-pop idols, athletes, and creators crowdfund billboards for birthdays, comebacks, anniversaries, and milestones — turning city streets into tribute displays. And it’s become one of the most consistent, passionate buyers of outdoor media in the world.

The scale of fan outdoor spending

This isn’t a handful of superfans. It’s a global, organized economy:

• Fan groups routinely fundraise for Times Square billboard spots, where a prime-time 15-second-per-hour slot runs roughly $30,000 for a week.
• Celebrations span multiple cities and countries simultaneously — one anniversary campaign ran billboard projects across 40 countries, and another lit up screens in 11 world cities on the same day.
• The most devoted fandoms fund multi-screen packages: TSX and Broadway Beacon spectaculars in Times Square, LED trucks, subway and transit ads, and landmark screens in Seoul, Tokyo, Shanghai, and beyond.

Why outdoor is the fan medium of choice

Fans choose outdoor because it’s public. A digital ad seen only by the fan who paid for it defeats the purpose; a billboard seen by thousands — and photographed and shared — is a statement.

Two dynamics make it work:

• Attention from the star. Idols frequently acknowledge and repost fan billboard campaigns, closing the loop and fueling more.
• Social amplification. Fans photograph landmark screens and flood social media, so the “ad” becomes cultural content.

The economics align with the data on outdoor: 74% of mobile users take action after seeing a DOOH ad, and 86% ad recall means these tributes actually get remembered — by the public and the idol alike.

What fan campaigns prove about outdoor

Fan campaigns are a live demonstration of principles every brand should notice:

1. Outdoor builds belonging. A billboard makes fans feel they’ve “made it” for their idol. Brands can use the same public, symbolic power to build community.

2. Landmarks multiply value. The same budget on a roadside sign doesn’t create a moment; the same budget on a Times Square screen creates global news. Location is the strategy.

3. Crowdfunding proves demand. Tens of thousands of individual fans funding one billboard is a crowd-validated commitment brands would kill for.

4. Physical moments go digital. The filmed-and-shared nature of outdoor means a single placement produces weeks of social content — a lesson in planning creative for the second screen.

The business lesson for brands

You don’t need an idol to use this playbook. The fan economy demonstrates the ceiling of what public, landmark, emotionally-charged outdoor can do — and brands can borrow the mechanics:

• Turn a launch into a public event people want to photograph.
• Use landmark screens for moments that matter, not routine messaging.
• Design creative that gets shared, because the physical placement is the start, not the end.
• Let your community participate — a brand’s most loyal customers respond to public celebration just like fandoms do.

The expertise behind the scenes

Running a fan campaign across countries isn’t as simple as it looks. It requires booking landmark inventory weeks in advance, managing multi-city logistics, handling time zones, and making sure creative displays correctly on every screen type. That’s specialized work.

It’s work Globalstars does daily. We help fandoms and entertainment brands place campaigns on the world’s most visible screens — from Times Square and Piccadilly to city-center LEDs across Asia — handling the planning, media buying, and execution so the fans can focus on celebrating.
