Top fan-driven outdoor campaigns in Hong Kong

07/10/2026 Michelle Lau

Hong Kong is home to a truly unique cultural phenomenon where dedicated fan clubs leverage crowdfunding to book prominent advertising spaces, including trams, buses, billboards, and Digital Out-of-Home (DOOH) screens, to publicly celebrate their idols. The financial scale of these media buys is remarkable, with campaigns ranging from HK$100,000 for a single wrapped bus to well over HK$2 million for expansive, city wide birthday spectacles.

The sheer density of these fan organized campaigns is so significant that during late April, the bustling district of Causeway Bay is affectionately dubbed "Keung To Bay." While this vibrant trend was originally popularized by the passionate fan clubs of the local boy band MIRROR, it has since grown far beyond its roots, expanding to include massive K-pop fandoms and even gaming communities.

What is fan-driven OOH advertising?

Fan-driven OOH is outdoor advertising funded and organised by fan clubs rather than brands. The goal is not to sell a product, it is to celebrate an idol, mark a birthday, promote a new release, or make a public statement of support at a scale that turns heads.

In most cities, fan campaigns mean trending hashtags and social media posts. In Hong Kong, they mean wrapped trams, full bus body ads, Causeway Bay billboards and DOOH screens, the kind of media buys competing brands spend months planning.

The money comes from crowdfunding, typically organised through Telegram groups that can number in the thousands. Campaigns are planned weeks or months in advance, coordinated with precision, and often tied to charitable giving to amplify cultural meaning alongside visibility.

Why Hong Kong is the global capital of fan-led campaigns

Two things explain it: the density of Hong Kong's OOH landscape and the organisational culture of its fan clubs.

Hong Kong packs a remarkable concentration of high impact outdoor inventory into a compact geography. The MTR moves roughly 1.7 billion passengers a year. Trams run down Hennessy Road through Causeway Bay multiple times daily. Buses cover every district. Causeway Bay alone concentrates landmark LED screens, billboards and DOOH panels within a single walkable area. For a fan club, booking a tram wrap and a Causeway Bay billboard simultaneously means a campaign that tens of thousands of people pass every day without trying to find it.

Then add Xiaohongshu. Fan campaigns are photographed obsessively and shared across the platform, turning a two-week physical placement into weeks of online reach extending deep into mainland China and beyond. A campaign seen in person by 50,000 people in Causeway Bay can reach millions once it circulates on social feeds. The Adintime HK guide to Xiaohongshu advertising covers how this platform fits into HK advertising more broadly.

Fan clubs in HK are also genuinely organised. Groups of 2,000+ members coordinate via Telegram, splitting contributions, assigning roles and managing media owner relationships with the kind of rigour most small brands would struggle to match.

Keung To: from a single tram to a city wide spectacle

Keung To, member of Cantopop boy band MIRROR, is the artist most associated with fan-driven OOH in Hong Kong. Causeway Bay is informally called "Keung To Bay" during his late April birthday, a nickname earned campaign by campaign.

2021, 22nd birthday: tram wrap between Shek Tong Shui and North Point, bus stop billboards, LED panels at seven locations including SOGO Causeway Bay and near Chungking Mansions in TST. Total estimated spend: around HK$500,000.

2022, 23rd birthday: the fan club sponsored a Free Ride Day on the entire tram network for all passengers in Hong Kong, something Hong Kong Tramways described as unprecedented. Combined with charity pop-up shops in Causeway Bay and TST, and billboards in London, New York and Singapore, the campaign became an international media event.

2024, 25th birthday: five dedicated birthday trams across Hong Kong Island, LED screens at Times Square and SOGO TV on Matheson Street, billboards at Hang Lung Centre and Golden Gateway, and simultaneous LED campaigns at Tee Mall in Guangzhou by mainland fans. Thousands gathered in Causeway Bay on the day.

For a detailed breakdown of the 2024 campaign, see the Adintime HK article on Keung To's 25th birthday bash.

Anson Lo: the HK$1 million birthday campaign

Anson Lo, another frontline member of MIRROR, set a different kind of benchmark. For his 26th birthday, fans spent over HK$1 million across multiple formats, including LED lighting on a cruise ship in Victoria Harbour and a giant billboard at the TST Star Ferry Pier.

The TST billboard later attracted McDonald's Hong Kong, which rented the same space to launch an endorsement campaign featuring Anson Lo. It is one of the clearest documented examples of a fan campaign directly influencing a brand's media buying decision.

Separately, fans paid over HK$100,000 to wrap two buses on routes 2A and 106 on Hong Kong Island, interior and exterior both covered, to celebrate the premiere of his TV episode "Sometimes When We Touch."

KCON 2024: K-pop fans take over the Airport Express

KCON's Hong Kong debut in March 2024, held at AsiaWorld-Expo, triggered a wave of K-pop fan campaigns at the Airport Express AsiaWorld-Expo station. Concourse lightboxes were booked by fan clubs for ATEEZ, aespa, 章昊 (Zhang Hao) and J01, turning the station into a fanchant advertising showcase for the duration of the event.

The Airport Express choice made tactical sense: it is the main transit route for international visitors to AsiaWorld-Expo, giving campaigns a captive audience of concert goers arriving and departing.

The broader MIRROR ecosystem and what came after

Beyond the headline cases, fan OOH campaigns have become routine across MIRROR's full roster and beyond. Edan Lui's fans booked bus shelter ads for a new song release. Artists from Collar, Anson Kong and Cloud Wan have had bus and tram campaigns organised by fan clubs. The format has also migrated into anime and gaming fandoms, MTR lightboxes and bus stop panels for character anniversaries and game launches.

What these campaigns have in common

Strategic location clusters: Causeway Bay, TST and key MTR stations for maximum footfall
Layered formats: tram + bus + billboard + DOOH running simultaneously for saturation effect
Charitable mechanics: donations triggered by social engagement, extending press reach
Design built for the photo, conceived as content first, format second

Fan culture in Hong Kong has produced something advertising agencies rarely pull off: campaigns people actively seek out. No brand budget involved. No media planner. Just a fan club, a crowdfunding group chat, and a remarkably good understanding of Hong Kong's outdoor media landscape.

What started as a birthday tram wrap for Keung To has become a distinct genre of OOH advertising, one that Adintime HK has helped fan clubs execute across billboards, buses and DOOH screens across the city.

The formats fan clubs use most, and what they cost

Tram wraps remain the most iconic fan campaign format. A tram along Hennessy Road passes through Causeway Bay multiple times daily in front of extremely high foot traffic. Bus and tram advertising inventory is available on Adintime HK.

Full bus body ads (KMB, Citybus) typically cost HK$50,000–100,000+ per bus for a full exterior wrap. Fan clubs routinely book two or more simultaneously. Interior wraps, seat backs, ceiling panels, can be added to create an immersive experience passengers photograph on board.

Billboards in Causeway Bay and TST are the most prestigious placements. LED screens at landmark sites (SOGO TV wall, Hang Lung Centre, TST Star Ferry Pier) command HK$100,000 – 400,000 per month and attract media attention. The Adintime HK outdoor advertising cost report has a full breakdown by format and district.

DOOH screens add motion and creative flexibility, animated birthday messages, video content, dynamic countdowns. Digital OOH options on Adintime HK cover key screens across HK districts.

MTR lightboxes work well for event based campaigns around concert venues (AsiaWorld-Expo) and idol associated districts (Causeway Bay, TST). Concourse panels offer dwell time that outdoor billboards cannot match.

A mid-scale fan campaign, one tram, two buses, a Causeway Bay billboard and a DOOH run, starts around HK$300,000–500,000 all-in including production. Large multi-format campaigns routinely exceed HK$1 million.

How fan campaigns create brand ripple effects

Fan-driven OOH campaigns do something most brand campaigns struggle with: they generate genuine press coverage. Marketing Interactive, HK01 and coconuts.co regularly cover major fan campaigns, delivering editorial reach on top of paid placement at no additional cost to the fan club.

The McDonald's and Anson Lo case is the clearest example. When fans occupy a premium TST billboard with enough visibility to become a local event, brands paying attention to the same audiences notice the proof of concept. In multiple cases, fan campaigns for MIRROR members preceded or directly influenced brand endorsement deals.

For brands in adjacent categories, youth fashion, F&B, entertainment, fan campaigns are also useful competitive intelligence. If a fan club can spend HK$1 million and generate press coverage and Xiaohongshu virality, those same placements carry a reach that justifies brand level investment.

Planning your own fan-driven campaign

Book early. Premium Causeway Bay and TST locations sell weeks in advance, especially during Chinese New Year (January-February) and summer (June-August). Start conversations 2–3 months ahead for a major birthday campaign.

Design for the photo, not the format. Fan campaigns succeed or fail on Xiaohongshu and Instagram. Bold colour, clear imagery and a readable message at a glance, that is the template that circulates.

Layer formats across districts. A tram, two buses and a Causeway Bay billboard running simultaneously creates a grid of locations where fans can photograph and share from multiple neighbourhoods. Coverage density multiplies social reach.

Tie in a cause. Fan clubs that link campaigns to charitable donations triggered by social engagement thresholds earn a second wave of press coverage and platform sharing that pure OOH cannot generate alone.

FAQ

1. What is fan-driven OOH advertising?

Fan-driven OOH is outdoor advertising, trams, buses, billboards, DOOH screens, funded and organised by fan clubs rather than brands. The goal is to celebrate or promote a favourite artist or event at public scale, with no commercial sponsor involved.

2. Why is Hong Kong particularly active in fan-led OOH campaigns?

Hong Kong has a high concentration of impactful, accessible outdoor formats (trams, buses, Causeway Bay billboards, MTR stations) combined with organised fan club culture and the viral power of Xiaohongshu. Physical campaigns in HK spread rapidly across mainland China and Southeast Asia via social media, making crowdfunded investment unusually effective.

3. How much does a fan-driven OOH campaign in Hong Kong cost?

A full bus wrap runs around HK$50,000–100,000. Tram wraps are in a similar range. A Causeway Bay or TST billboard can cost HK$100,000–400,000 per month. Multi format campaigns combining several of these have reached HK$1–2 million. A mid-scale campaign (one tram, two buses, one billboard) typically falls in the HK$300,000–500,000 range all-in.

4. Which formats are most popular for fan campaigns?

Tram wraps (Hennessy Road through Causeway Bay), full bus body ads, landmark LED screens (SOGO TV wall, TST Star Ferry Pier), DOOH panels and MTR lightboxes. The most impactful campaigns combine several formats to achieve district level saturation.

5. Can fan clubs book OOH advertising directly in Hong Kong?

Fan clubs can work through a media marketplace like Adintime HK, which aggregates inventory across media owners and simplifies booking. This is particularly useful for campaigns combining formats across different operators, trams, buses and billboards each have separate media owners.

6. Do fan-driven campaigns generate press coverage?

Yes, regularly. Major campaigns earn coverage in Marketing Interactive, HK01 and coconuts.co, and spread extensively on Xiaohongshu and Instagram. Campaigns tied to charitable donations tend to generate the most editorial attention.

7. Has any brand directly benefited from a fan campaign?

McDonald's Hong Kong booked the TST Star Ferry Pier billboard previously used for Anson Lo's fan campaign to launch its own endorsement campaign with Anson Lo, a direct case of a brand following fan-driven advertising momentum.

8. When is the best time to run a fan campaign in Hong Kong?

Outside of birthday dates, avoid booking premium OOH without early reservation during Chinese New Year (January-February) and summer concert season (June-August). For event-based campaigns (KCON, concerts at AsiaWorld-Expo), book at least 2–3 months ahead to secure the closest stations and formats.
