The posters used are typically made of a lightweight paper and printed usingflexography, digital printing andscreen printing. Modern printing techniques enable the posters to feature full-colour designs, halftones, and photographs, making them popular for advertising concerts, political messages, commercial advertisements and special events. An increasing number of posters do not advertise anything at all and instead feature artwork, inspirational or positive messages, and religious messages.^{[citation needed]}

It is an advertising tactic mostly used by small businesses promoting concerts andpolitical activist groups, but there have been occasions where international companiessubcontracted local advertising agencies for flyposting jobs in order not to get caught in illegal behavior, as a form ofguerrilla marketing. In 2004,Sony Music andBMG were threatened withanti-social behaviour orders byCamden Borough Council for illegal flyposting.^[1]

In many countries, it is illegal to place such posters onprivate property without the consent of the property owner, or to post onpublic property without a sign permit from the local government. Some areas, however, have publicbulletin boards where notices may be posted.^[2]

In an effort to discourage illegal flyposting, surfaces at risk of it are sometimes permanently signedPost No Bills (US),No Flyposting (UK), orDéfense d'afficher - loi du 29 juillet 1881 (France), a reference to a lawpassed in 1881 that regulates the display of advertisements in public spaces.

While flyposting is commonplace, it is often viewed as a nuisance bylandlords and they can takecivil action to protect theirproperty rights. A particularly noteworthy incident of this type occurred inBoston, Massachusetts. In the case of the2007 Boston Mooninite panic, advertisers had placed electronic signboards without notifying local authorities, prompting a costly reaction by theBoston Police Department bomb squad when the signs were mistaken for bombs.^[3]

With the rise of theWorld Wide Web, much of advertising has been shifted online. Someadvertising agencies have drawn similarities between flyposting and certain types ofadware, which are more invasive toconsumers.^[4]
