A small sticker on a city window can sometimes expose the raw reality of our society's public communication and advertising ethics. The promotional sticker for the SBS drama Taxi Driver, which read "Don't die, get revenge. We'll solve it for you" along with a clear phone number, is precisely that evidence. Inside buses that serve as daily transportation for countless citizens, this message transcends the fictional world and penetrates into the language of reality. A citizen's social media post saying "I almost called for real" is not merely a joke. This raises a critical question of urban communication: how do messages thrown into the public space of the city relate to citizens' emotions, and what legal and ethical responsibilities should they bear?
The City as a Massive Media Ecosystem
The city is a vast media ecosystem. From digital signage on buildings along the roads to screen doors in subways and seats and windows on buses, every space constantly speaks and is exposed to an unspecified multitude. When the city operates as one giant communication environment, what becomes most important is the "location" and "context" where messages are placed. The same phrase can trigger citizens' emotions and actions in entirely different directions depending on where it is positioned. Bus windows, in particular, are exposed defenseless to children, adolescents, the elderly, and socially vulnerable populations in a mobile environment devoid of personal space. The first principle of advertising ethics—that messages in public places must always be designed with "the most vulnerable person" in mind—originates precisely here.
The Boundaries of Law and Ethical Gaps: Where Is Korea's Advertising Regulation?
The biggest problem with this sticker is that, contrary to its original intent as drama promotion, it lost its narrative context in public spaces and functioned as a realistic directive with only the text remaining. The phrase "Don't die, get revenge" summons high-risk words such as "revenge," "retaliation," and "death" into everyday spaces, beyond the metaphorical narrative within the drama. Such messages can act as triggers that amplify anxiety for those with memories of violence and provide unnecessary psychological stimulation to citizens experiencing extreme stress.
So did the law fail to prevent this? While Korea has various regulations, clever blind spots exist. First, the "Act on the Management of Outdoor Advertisements and Promotion of the Outdoor Advertising Industry" stipulates that it "preserves public morals and prevents harm to the public" and prohibits advertisements that "justify criminal acts or express them cruelly." However, this law mainly focuses on traditional "outdoor" advertisements such as building exteriors or public facilities, and its application to sticker advertisements "inside" buses may be ambiguous.
From the perspective of broadcast content advertising, we can examine the "Regulations on Broadcasting Review." Article 36 (Violence Depiction) strictly prohibits excessive violence, and Article 38-2 (Suicide Depiction) strictly prohibits "expressions that glorify or justify suicide." Even if the drama itself complied with these regulations, regulation of the "derivative effects" when its promotional materials are exposed in public places without context is insufficient. Additionally, the "Youth Protection Act" regulates the distribution of media harmful to youth, but it also faces procedural limitations in designating and immediately regulating individual sticker advertisements inside buses as "harmful media." Ultimately, while principles of various laws exist, "regulatory gaps" like this case occur at the boundary points where they intersect.
How Do Other Countries Manage This? Cases from London and New York
This problem is not unique to Korea. However, major cities abroad have established clearer and stronger ethical and institutional mechanisms. The advertising policy of Transport for London (TfL), London's transport authority, is very instructive. TfL clearly prohibits advertisements that cause serious or widespread offense to the public or are socially inappropriate. Particularly since 2019, it has completely banned advertisements for high-fat, high-salt, high-sugar (HFSS) foods harmful to health and restricted advertisements promoting unrealistic body images, actively operating advertising policies to protect citizens' physical and mental health. This reflects the philosophy that public transportation is not merely a space for movement but a public environment that affects citizens' well-being.
New York's MTA (Metropolitan Transportation Authority) also made a decision in 2015 to ban all "political issue advertisements" after litigation surrounding advertisements with concerns about inciting violence. This is an important precedent showing that even in American society, which values freedom of expression, the safety and order maintenance of public transportation spaces can take priority. The focus was on blocking the "potential threat" citizens might feel rather than the "intent" of the advertisement. Furthermore, regarding sensitive topics such as suicide, the World Health Organization (WHO) provides guidelines for media professionals. These guidelines strongly recommend avoiding specific descriptions of suicide methods and not glorifying suicide or presenting it as a simple problem-solving solution. Korea also presents similar principles through the "Suicide Reporting Guidelines" by the Ministry of Health and Welfare and the Korea Suicide Prevention Center. These ethical standards should be applied even more strictly to repeatedly exposed advertising messages, not just news reporting.
Toward New Ethics for Urban Media
Ultimately, the small sticker on the bus window reveals the structural problems facing Korea's urban media environment. Within the industrial logic where advertisers prioritize exposure maximization and media companies prioritize advertising revenue, citizens' psychological safety and public ethics are pushed aside as secondary issues. Laws and review regulations remain within their respective domains, and there is no control tower overseeing the publicity of messages from an integrated perspective of urban space.
Now, the responsibility of advertising must expand beyond simply promoting products or brands to practicing the ethics of urban communication. Urban media are directly connected to citizens' daily lives and have an obligation not to harm their emotions and safety. It is time to actively examine models like New York's MTA or London's TfL that establish clear advertising ethics guidelines and principally restrict advertisements containing high-risk words such as violence, retaliation, and death in public media such as subways, buses, and areas near schools.
Korea should also prepare "Urban Communication Safety Guidelines" considering city-specific and media-specific characteristics, and more strictly prohibit phrases that could pose risks when narrative context is removed, especially on public transportation frequently used by youth. A single sticker on a bus window is small, but its ripple effect is never small. This transcends the realm of simple promotional mistakes. Cities are no longer spaces solely for advertisers but social spaces where citizens' emotions live and breathe. Every sentence appearing in public places is accepted as part of reality, and that reality sometimes shakes an individual's psychology and society's entire sensibility.
The core of urban communication ultimately converges on one sentence: urban media are voices speaking to citizens, and those voices must take responsibility.
