自动化+大数据，户外广告逆势增长
大多数传统广告形式面对网络广告的兴起节节败退，可户外广告牌却在此时迎来了第二春。户外广告（OOH）预计将在2018年增长3.4%，而数字户外广告（DOOH）将增长16%。通过智能手机数据打通线上与线下的广告牌公司有望实现高度相关的精准投放。支持者表示，户外广告会越来越像网络广告那样，根据受众、观看次数以及位置来购买，这在数据驱动的“程序化广告牌”模式中尤为有效。
户外广告
Outdoor advertising
时代的标志
Sign of the times
Most forms of conventional advertising—print, radio and broadcast television—have been losing ground to online ads for years; only billboards, dating back to the 1800s, and TV ads are holding their own

PEDESTRIANS STROLLING down 8th Avenue in Manhattan’s Hell’s Kitchen neighbourhood will be struck by the cast-limestone façade of the Hearst Magazine Building. Commissioned by William Randolph Hearst in 1926, the 40,000-square- foot (3,716-square-metre) art deco building is adorned with fluted columns and statues and topped by a 600-foot (183-metre) glass and steel skyscraper. Another conspicuous feature is a vast digital screen transmitting advertisements from BuzzFeed, ESPN and Vice. This blend of history and modernity is emblematic of the outdoor-advertising business itself, which, despite being one of the world’s oldest forms of marketing is embracing digital technologies.
当行人漫步在曼哈顿中城八大道位于地狱厨房这一段，会被赫斯特杂志集团大楼（Hearst Magazine Building）的混凝土石灰石外立面震撼。这栋大楼由威廉·伦道夫·赫斯特（William Randolph Hearst）于1926年委托设计，3716平方米的装饰艺术风格建筑带有凹槽柱和雕像。在它上面是一栋183米高的玻璃和钢结构大厦。它的另一个突出特点是一块巨型数字屏幕，不断播放着来自BuzzFeed、ESPN和Vice的广告。这种历史与现代的混合是户外广告业务本身的典型特征。尽管这种广告是世界上最古老的营销形式之一，但它正在拥抱数字技术。
Most forms of conventional advertising—print, radio and broadcast television—have been losing ground to online ads for years; only billboards, dating back to the 1800s, and TV ads are holding their own (see chart). Such out-of-home (OOH) advertising, as it is known, is expected to grow by 3.4% in 2018, and digital out-of-home (DOOH) advertising, which includes the LCD screens found in airports and shopping malls, by 16%. Such ads draw viewers’ attention from phones and cannot be skipped or blocked, unlike ads online.
多年来，印刷、广播和无线电视等大多数传统广告形式面对网络广告的兴起节节败退，只有可追溯至19世纪的广告牌以及有线电视广告仍然坚守阵地（见图表）。户外广告（OOH）预计将在2018年增长3.4%，而包括机场和购物中心液晶显示屏在内的数字户外广告（DOOH）将增长16%。这类广告把受众注意力从手机上吸引过来，而且不能像网络广告那样可被跳过或屏蔽。
Billboard owners are also making hay（抓紧时机） from the location data that are pouring off people’s smartphones. Information about their owners’ whereabouts and online browsing gets aggregated and anonymised by carriers and data vendors and sold to media owners. They then use these data to work out when different demographic groups—“business travellers”, say—walk by their ads. That knowledge is added to insights into traffic, weather and other external data to produce highly relevant ads. DOOH providers can deliver ads for coffee when it is cold and fizzy drinks when it is warm. Billboards can be programmed to show ads for allergy medication when the air is full of pollen.
广告牌公司也在积极利用从人们的智能手机上得到的大量位置数据。有关手机用户的行踪和在线浏览的信息由运营商和数据供应商汇总并做匿名处理，再出售给媒体所有者。然后它们利用这些数据计算出不同的人口群体（比如“商务旅客”）何时经过它们的广告牌。把这些信息添加到对交通、天气和其他外部数据的洞察中，就可以生成高度相关的广告。DOOH供应商可以在天气寒冷时播放咖啡广告，在炎热时打出碳酸饮料广告，还可以给广告牌编程，让它们在空气中满是花粉时播放抗过敏药物的广告。
Such targeting works particularly well when it is accompanied by “programmatic” advertising methods, a term that describes the use of data to automate and improve ads. In the past year billboard owners such as Clear Channel and JCDecaux have launched programmatic platforms which allow brands and media buyers to select, purchase and place ads in minutes, rather than days or weeks. Industry boosters say outdoor ads will increasingly be bought like online ones, based on audience and views as well as location.
这种定向广告在与“程序化”广告方法结合时尤为有效。程序化广告就是利用数据来实现广告的自动化及改进。过去一年里，清晰频道（Clear Channel）和德高集团（JCDecaux）等广告牌公司推出了程序化广告平台，让品牌和媒体买家按分钟选择、购买和投放广告，而不是按天或按周。行业支持者表示，户外广告会越来越像网络广告那样，根据受众、观看次数以及位置来购买。
That is possible because billboard owners claim to be able to measure how well their ads are working, even though no “click-through” rates are involved. Data firms can tell advertisers how many people walk past individual advertisements at particular times of the day. Advertisers can estimate how many individuals exposed to an ad for a Louis Vuitton handbag then go on to visit a nearby shop (or website) and buy the product. Such metrics make outdoor ads more data-driven, automated and measurable, argues Michael Provenzano, co-founder of Vistar Media, an ad-tech firm in New York.
这是有可能的，因为广告牌公司声称，即使没有“点击率”信息，它们也能衡量广告的效果。数据公司可以告诉广告商有多少人在一天中某段时间里走过某个广告牌。广告商可以估计出在看到一则路易威登手提包广告后立即到附近一家商店（或网站上）购买的人数。纽约广告科技公司Vistar Media的联合创始人迈克尔·普罗温扎诺（Michael Provenzano）认为，这些指标让户外广告更多由数据驱动、更自动化，效果也更可测量。
As the outdoor-ad industry becomes more data-driven, tech giants are among those to see more value in it. Netflix recently acquired a string of billboards along Hollywood’s Sunset Strip, where it will start advertising its films and TV shows. Tech firms, among them Apple and Google, are heavy buyers of OOH ads, accounting for 25 of the top 100 OOH ad spenders in America.
随着户外广告行业变得更多由数据驱动，科技巨头也更多地看到了它的价值。Netflix最近收购了好莱坞日落大道上的一排广告牌，准备开始宣传它制作的影视节目。包括苹果和谷歌在内的科技公司是OOH广告的重要买家，美国前100大户外广告客户中有25家是科技公司。
The outdoor-ad revolution is not problem-free. The collection of mobile-phone data raises privacy concerns. And criticisms of the online-ad business for being opaque, and occasionally fraudulent, may also be lobbed at the OOH business as it becomes bigger and more complex. The industry is ready to address such concerns, says Jean-Christophe Conti, chief executive of VIOOH, a media-buying platform. One of the benefits of following the online-ad trailblazers, he notes, is learning from their blunders.
然而户外广告革命并非没有问题。收集手机数据引起了对隐私问题的担忧。而随着OOH广告业务规模越来越大、越来越复杂，对网络广告业务不透明、有时涉嫌欺诈的批评也可能指向OOH业务。媒体采购平台VIOOH的首席执行官让-克里斯托夫•孔蒂（Jean-Christophe Conti）表示，业界已准备好处理这些问题。他指出，追随网络广告开拓者的好处之一就是从它们的错误中学习。■
