Advertising is a form of communication that typically attempts to persuade potential customers to purchase or to consume more of a particular brand of product or service. Many advertisements are designed to generate increased consumption of those products and services through the creation and reinforcement of "brand image" and "brand loyalty". For these purposes, advertisements sometimes embed their persuasive message with factual information. Every major medium is used to deliver these messages, including television, radio, cinema, magazines, newspapers, video games, the Internet and billboards. Advertising is often placed by an advertising agency on behalf of a company or other organization.

Organizations that frequently spend large sums of money on advertising that sells what is not, strictly speaking, a product or service include political parties, interest groups, religious organizations, and military recruiters. Non-profit organizations are not typical advertising clients, and may rely on free modes of persuasion, such as public service announcements.

Advertising spending has increased dramatically in recent years. In 2006, spending on advertising has been estimated at $155 billion in the United States[1] and $385 billion worldwide[2], and the latter to exceed $500 billion by 2010.

While advertising can be seen as necessary for economic growth, it is not without social costs. Unsolicited Commercial Email and other forms of spam have become so prevalent as to have become a major nuisance to users of these services, as well as being a financial burden on internet service providers.[3] Advertising is increasingly invading public spaces, such as schools, which some critics argue is a form of child exploitation.[4]

History

Advertising catch phrase: “buy me and you'll get a good bargain”. Attic black-figured lekythos, ca. 500 BC.

Egyptians used papyrus to make sales messages and wall posters. Commercial messages and political campaign displays have been found in the ruins of Pompei and ancient Arabia. Lost and found advertising on papyrus was common in Ancient Greece and Ancient Rome. Wall or rock painting for commercial advertising is another manifestation of an ancient advertising form, which is present to this day in many parts of Asia, Africa, and South America. The tradition of wall painting can be traced back to Indian rock art paintings that date back to 4000 BCE.[5]

As the towns and cities of the Middle Ages began to grow, and the general populace was unable to read, signs that today would say cobbler, miller, tailor or blacksmith would use an image associated with their trade such as a boot, a suit, a hat, a clock, a diamond, a horse shoe, a candle or even a bag of flour. Fruits and vegetables were sold in the city square from the backs of carts and wagons and their proprietors used street callers or town criers to announce their whereabouts for the convenience of the customers.

As education became an apparent need and reading, as well printing developed, advertising expanded to include handbills. In the 17th century advertisements started to appear in weekly newspapers in England. These early print advertisements were used mainly to promote books and newspapers, which became increasingly affordable with advances in the printing press; and medicines, which were increasingly sought after as disease ravaged Europe. However, false advertising and so-called "quack" advertisements became a problem, which ushered in the regulation of advertising content.

As the economy expanded during the 19th century, advertising grew alongside. In the United States, the success of this advertising format eventually led to the growth of mail-order advertising.

In June 1836, French newspaper La Presse is the first to include paid advertising in its pages, allowing it to lower its price, extend its readership and increase its profitability and the formula was soon copied by all titles. Around 1840, Volney Palmer established a predecessor to advertising agencies in Boston.[6] Around the same time, in France, Charles-Louis Havas extended the services of his news agency, Havas to include advertisement brokerage, making it the first French group to organize. At first, agencies were brokers for advertisement space in newspapers. N. W. Ayer & Son was the first full-service agency to assume responsibility for advertising content. N.W. Ayer opened in 1869, and was located in Philadelphia.[6]

At the turn of the century, there were few career choices for women in business; however, advertising was one of the few. Since women were responsible for most of the purchasing done in their household, advertisers and agencies recognized the value of women's insight during the creative process. In fact, the first American advertising to use a sexual sell was created by a woman – for a soap product. Although tame by today's standards, the advertisement featured a couple with the message "The skin you love to touch".[7]

In the early 1920s, the first radio stations were established by radio equipment manufacturers and retailers who offered programs in order to sell more radios to consumers. As time passed, many non-profit organizations followed suit in setting up their own radio stations, and included: schools, clubs and civic groups.[8] When the practice of sponsoring programs was popularised, each individual radio program was usually sponsored by a single business in exchange for a brief mention of the business' name at the beginning and end of the sponsored shows. However, radio station owners soon realised they could earn more money by selling sponsorship rights in small time allocations to multiple businesses throughout their radio station's broadcasts, rather than selling the sponsorship rights to single businesses per show.

This practice was carried over to television in the late 1940s and early 1950s. A fierce battle was fought between those seeking to commercialise the radio and people who argued that the radio spectrum should be considered a part of the commons – to be used only non-commercially and for the public good. The United Kingdom pursued a public funding model for the BBC, originally a private company, the British Broadcasting Company, but incorporated as a public body by Royal Charter in 1927. In Canada, advocates like Graham Spry were likewise able to persuade the federal government to adopt a public funding model, creating the Canadian Broadcasting Corporation. However, in the United States, the capitalist model prevailed with the passage of the Communications Act of 1934 which created the Federal Communications Commission.[8] To placate the socialists, the U.S. Congress did require commercial broadcasters to operate in the "public interest, convenience, and necessity".[9] Public broadcasting now exists in the United States due to the 1967 Public Broadcasting Act which led to the Public Broadcasting Service and National Public Radio.

In the early 1950s, the DuMont Television Network began the modern trend of selling advertisement time to multiple sponsors. Previously, DuMont had trouble finding sponsors for many of their programs and compensated by selling smaller blocks of advertising time to several businesses. This eventually became the standard for the commercial television industry in the United States. However, it was still a common practice to have single sponsor shows, such as The United States Steel Hour. In some instances the sponsors exercised great control over the content of the show - up to and including having one's advertising agency actually writing the show. The single sponsor model is much less prevalent now, a notable exception being the Hallmark Hall of Fame.

The 1960s saw advertising transform into a modern approach in which creativity was allowed to shine, producing unexpected messages that made advertisements more tempting to consumers' eyes. The Volkswagen ad campaign—featuring such headlines as "Think Small" and "Lemon" (which were used to describe the appearance of the car)—ushered in the era of modern advertising by promoting a "position" or "unique selling proposition" designed to associate each brand with a specific idea in the reader or viewer's mind. This period of American advertising is called the Creative Revolution and its archetype was William Bernbach who helped create the revolutionary Volkswagen ads among others. Some of the most creative and long-standing American advertising dates to this period.

The late 1980s and early 1990s saw the introduction of cable television and particularly MTV. Pioneering the concept of the music video, MTV ushered in a new type of advertising: the consumer tunes in for the advertising message, rather than it being a by-product or afterthought. As cable and satellite television became increasingly prevalent, specialty channels emerged, including channels entirely devoted to advertising, such as QVC, Home Shopping Network, and ShopTV Canada.

Marketing through the Internet opened new frontiers for advertisers and contributed to the "dot-com" boom of the 1990s. Entire corporations operated solely on advertising revenue, offering everything from coupons to free Internet access. At the turn of the 21st century, a number of websites including the search engine Google, started a change in online advertising by emphasizing contextually relevant, unobtrusive ads intended to help, rather than inundate, users. This has led to a plethora of similar efforts and an increasing trend of interactive advertising.

The share of advertising spending relative to GDP has changed little across large changes in media. For example, in the U.S. in 1925, the main advertising media were newspapers, magazines, signs on streetcars, and outdoor posters. Advertising spending as a share of GDP was about 2.9 percent. By 1998, television and radio had become major advertising media. Nonetheless, advertising spending as a share of GDP was slightly lower—about 2.4 percent.[10]

A recent advertising innovation is "guerrilla marketing", which involve unusual approaches such as staged encounters in public places, giveaways of products such as cars that are covered with brand messages, and interactive advertising where the viewer can respond to become part of the advertising message. This reflects an increasing trend of interactive and "embedded" ads, such as via product placement, having consumers vote through text messages, and various innovations utilizing social network services such as MySpace.

Mobile billboard advertising

Good Year Blimp has a distinctive yellow stripe under the logo to catch people's attention.

Mobile billboards are truck- or blimp-mounted billboards or digital screens. These can be dedicated vehicles built solely for carrying advertisements along routes preselected by clients, or they can be specially-equipped cargo trucks. The billboards are often lighted; some being backlit, and others employing spotlights. Some billboard displays are static, while others change; for example, continuously or periodically rotating among a set of advertisements.

Mobile displays are used for various situations in metropolitan areas throughout the world, including:

Public service advertising

The same advertising techniques used to promote commercial goods and services can be used to inform, educate and motivate the public about non-commercial issues, such as AIDS, political ideology, energy conservation, religious recruitment, and deforestation.

Advertising, in its non-commercial guise, is a powerful educational tool capable of reaching and motivating large audiences. "Advertising justifies its existence when used in the public interest - it is much too powerful a tool to use solely for commercial purposes." - Attributed to Howard Gossage by David Ogilvy

Public service advertising, non-commercial advertising, public interest advertising, cause marketing, and social marketing are different terms for (or aspects of) the use of sophisticated advertising and marketing communications techniques (generally associated with commercial enterprise) on behalf of non-commercial, public interest issues and initiatives.

In the United States, the granting of television and radio licenses by the FCC is contingent upon the station broadcasting a certain amount of public service advertising. To meet these requirements, many broadcast stations in America air the bulk of their required public service announcements during the late night or early morning when the smallest percentage of viewers are watching, leaving more day and prime time commercial slots available for high-paying advertisers.

Public service advertising reached its height during World Wars I and II under the direction of several governments.

Types of advertising

Media

Paying people to hold signs is one of the oldest forms of advertising, as with this Human directional pictured above

Commercial advertising media can include wall paintings, billboards, street furniture components, printed flyers and rack cards, radio, cinema and television adverts, web banners, mobile telephone screens, shopping carts, web popups, skywriting, bus stop benches, human billboards, magazines, newspapers, town criers, sides of buses, banners attached to or sides of airplanes ("logojets"), in-flight advertisements on seatback tray tables or overhead storage bins, taxicab doors, roof mounts and passenger screens, musical stage shows, subway platforms and trains, elastic bands on disposable diapers, stickers on apples in supermarkets, shopping cart handles (grabertising), the opening section of streaming audio and video, posters, and the backs of event tickets and supermarket receipts. Any place an "identified" sponsor pays to deliver their message through a medium is advertising.

One way to measure advertising effectiveness is known as Ad Tracking. This advertising research methodology measures shifts in target market perceptions about the brand and product or service. These shifts in perception are plotted against the consumers’ levels of exposure to the company’s advertisements and promotions.The purpose of Ad Tracking is generally to provide a measure of the combined effect of the media weight or spending level, the effectiveness of the media buy or targeting, and the quality of the advertising executions or creative.[11]

Covert advertising

Main article: Product placement

Covert advertising is when a product or brand is embedded in entertainment and media. For example, in a film, the main character can use an item or other of a definite brand, as in the movie Minority Report, where Tom Cruise's character John Anderton owns a phone with the Nokia logo clearly written in the top corner, or his watch engraved with the Bulgari logo. Another example of advertising in film is in I, Robot, where main character played by Will Smith mentions his Converse shoes several times, calling them "classics," because the film is set far in the future. I, Robot and Spaceballs also showcase futuristic cars with the Audi and Mercedes-Benz logos clearly displayed on the front of the vehicles. Cadillac chose to advertise in the movie The Matrix Reloaded, which as a result contained many scenes in which Cadillac cars were used. Similarly, product placement for Omega Watches, Ford, VAIO, BMW and Aston Martin cars are featured in recent James Bond films, most notably Casino Royale.

Television commercials

Main articles: Television advertisement and Music in advertising

The TV commercial is generally considered the most effective mass-market advertising format, as is reflected by the high prices TV networks charge for commercial airtime during popular TV events. The annual Super Bowl football game in the United States is known as the most prominent advertising event on television. The average cost of a single thirty-second TV spot during this game has reached $2.7 million (as of 2007).

The majority of television commercials feature a song or jingle that listeners soon relate to the product.

Virtual advertisements may be inserted into regular television programming through computer graphics. It is typically inserted into otherwise blank backdrops[12] or used to replace local billboards that are not relevant to the remote broadcast audience.[13] More controversially, virtual billboards may be inserted into the background[14] where none existing in real-life. Virtual product placement is also possible.[15][16]

Infomercials

There are two types of infomercials, described as long form and short form. Long form infomercials have a time length of 30 minutes. Short form infomercials are 30 seconds to 2 minutes long. Infomercials are also known as direct response television (DRTV) commercials or direct response marketing.

The main objective in an infomercial is to create an impulse purchase, so that the consumer sees the presentation and then immediately buys the product through the advertised toll-free telephone number or website. Infomercials describe, display, and often demonstrate products and their features, and commonly have testimonials from consumers and industry professionals.

Some well known companies in the infomercial business are Script to Screen, Hawthorne Direct, International Shopping Network and Guthy-Renker.

Celebrity advertising

Main article: Celebrity branding

This type of advertising focuses upon using celebrity power, fame, money, popularity to gain recognition for their products and promote specific stores or products. Advertisers often advertise their products, for example, when celebrities share their favourtie products or wear clothes by specific brands or designers. Celebrities are often involved in advertising campaigns such as television or print adverts to advertise specific or general products.

Newer media and advertising approaches

Increasingly, other media are overtaking television because of a shift towards consumer's usage of the Internet as well as devices such as TiVo.

Advertising on the World Wide Web is a recent phenomenon. Prices of Web-based advertising space are dependent on the "relevance" of the surrounding web content and the traffic that the website receives.

E-mail advertising is another recent phenomenon. Unsolicited bulk E-mail advertising is known as "spam".

Some companies have proposed placing messages or corporate logos on the side of booster rockets and the International Space Station. Controversy exists on the effectiveness of subliminal advertising (see mind control), and the pervasiveness of mass messages (see propaganda).

Unpaid advertising (also called word of mouth advertising), can provide good exposure at minimal cost. Personal recommendations ("bring a friend", "sell it"), spreading buzz, or achieving the feat of equating a brand with a common noun (in the United States, "Xerox" = "photocopier", "Kleenex" = tissue, "Vaseline" = petroleum jelly, "Hoover" = vacuum cleaner, and "Band-Aid" = adhesive bandage) — these can be seen as the pinnacle of any advertising campaign. However, some companies oppose the use of their brand name to label an object. Equating a brand with a common noun also risks turning that brand into a genericized trademark - turning it into a generic term which means that its legal protection as a trademark is lost.

As the mobile phone became a new mass media in 1998 when the first paid downloadable content appeared on mobile phones in Finland, it was only a matter of time until mobile advertising followed, also first launched in Finland in 2000. By 2007 the value of mobile advertising had reached $2.2 billion and providers such as Admob delivered billions of mobile ads.

More advanced mobile ads include banner ads, coupons, Multimedia Messaging Service picture and video messages, advergames and various engagement marketing campaigns. A particular feature driving mobile ads is the 2D Barcode, which replaces the need to do any typing of web addresses, and uses the camera feature of modern phones to gain immediate access to web content. 83 percent of Japanese mobile phone users already are active users of 2D barcodes.

A new form of advertising that is growing rapidly is social network advertising. It is online advertising with a focus on social networking sites. This is a relatively immature market, but it has shown a lot of promise as advertisers are able to take advantage of the demographic information the user has provided to the social networking site.

From time to time, The CW Television Network airs short programming breaks called "Content Wraps," to advertise one company's product during an entire commercial break. The CW pioneered "content wraps" and some products featured were Herbal Essences, Crest, Guitar Hero II, CoverGirl, and recently Toyota.

Effect on memories and behavior

"Half the money I spend on advertising is wasted; the trouble is, I don't know which half." - popular quote generally attributed to either John Wanamaker or William Lever; also one of the Wrigley people from the Wm. Wrigley Jr. Company.
Billboard, New York City, (2005). The ad says, "60 days of daylight for Apartment 6F."

The impact of advertising has been a matter of considerable debate and many different claims have been made in different contexts. During debates about the banning of cigarette advertising, a common claim from cigarette manufacturers was that cigarette advertising does not encourage people to smoke who would not otherwise. The (eventually successful) opponents of advertising, on the other hand, claim that advertising does in fact increase consumption.

According to many sources, the past experience and state of mind of the person subjected to advertising may determine the impact that advertising has. Children under the age of four may be unable to distinguish advertising from other television programmes, while the ability to determine the truthfulness of the message may not be developed until the age of eight.

Over the past 15 years a whole science of marketing analytics and marketing effectiveness has been developed to determine the impact of marketing actions on consumers, sales, profit and market share. Marketing mix modeling, direct response measurement and other techniques are included in this science.

Public perception of the medium

As advertising and marketing efforts become increasingly ubiquitous in modern Western societies, the industry has come under criticism from groups such as Adbusters via culture jamming which criticizes the media and consumerism using advertising's own techniques. The industry is accused of being one of the engines powering a convoluted economic mass production system which promotes consumption. Recognizing the social impact of advertising, Mediawatch-uk, a British special interest group, works to educate consumers about how they can register their concerns with advertisers and regulators. It has developed educational materials for use in schools.

Public interest groups are increasingly suggesting that access to the mental space targeted by advertisers should be taxed , in that at the present moment that space is being freely taken advantage of by advertisers with no compensation paid to the members of the public who are thus being intruded upon. This kind of tax would be a Pigovian tax in that it would act to reduce what is now increasingly seen as a public nuisance. Efforts to that end are gathering more momentum, with Arkansas and Maine considering bills to implement such a taxation. Florida enacted such a tax in 1987 but was forced to repeal it after six months, as a result of a concerted effort by national commercial interests, which withdrew planned conventions, causing major losses to the tourism industry, and canceled advertising, causing a loss of $12 million to the broadcast industry alone.

Regulation

Main article: Advertising regulation

In the US many communities believe that many forms of outdoor advertising blight the public realm.[17] As long ago as the 1960s in the US there were attempts to ban billboard advertising in the open countryside[18]. Cities such as São Paulo have introduced an outright ban[19] with London also having specific legislation to control unlawful displays.

There have been increasing efforts to protect the public interest by regulating the content and the influence of advertising. Some examples are: the ban on television tobacco advertising imposed in many countries, and the total ban of advertising to children under 12 imposed by the Swedish government in 1991. Though that regulation continues in effect for broadcasts originating within the country, it has been weakened by the European Court of Justice, which had found that Sweden was obliged to accept foreign programming, including those from neighboring countries or via satellite.

In Europe and elsewhere, there is a vigorous debate on whether (or how much) advertising to children should be regulated. This debate was exacerbated by a report released by the Kaiser Family Foundation in February 2004 which suggested that food advertising, such as that for fast foods, targeting children was an important factor in the epidemic of childhood obesity in the United States.

In many countries - namely New Zealand, South Africa, Canada, and many European countries - the advertising industry operates a system of self-regulation. Advertisers, advertising agencies and the media agree on a code of advertising standards that they attempt to uphold. The general aim of such codes is to ensure that any advertising is 'legal, decent, honest and truthful'. Some self-regulatory organizations are funded by the industry, but remain independent, with the intent of upholding the standards or codes like the Advertising Standards Authority in the UK.

In the UK most forms of outdoor advertising such as the display of billboards is regulated by the UK Town and County Planning system. Currently the display of an advertisement without consent from the Planning Authority is a criminal offense liable to a fine of £2,500 per offence. All of the major outdoor billboard companies in the UK have convictions of this nature.

Naturally , many advertisers view governmental regulation or even self-regulation as intrusion of their freedom of speech or a necessary evil. Therefore, they employ a wide-variety of linguistic devices to bypass regulatory laws (e.g. printing English words in bold and French translations in fine print to deal with the Article 12 of the 1994 Toubon Law limiting the use of English in French advertising).[20] The advertisement of controversial products such as cigarettes and condoms is subject to government regulation in many countries. For instance, the tobacco industry is required by law in most countries to display warnings cautioning consumers about the health hazards of their products. Linguistic variation is often used by advertisers as a creative device to reduce the impact of such requirements.

Future

Global advertising

Advertising has gone through five major stages of development: domestic, export, international, multi-national, and global. For global advertisers, there are four, potentially competing, business objectives that must be balanced when developing worldwide advertising: building a brand while speaking with one voice, developing economies of scale in the creative process, maximising local effectiveness of ads, and increasing the company’s speed of implementation. Born from the evolutionary stages of global marketing are the three primary and fundamentally different approaches to the development of global advertising executions: exporting executions, producing local executions, and importing ideas that travel.[21]

Advertising research is key to determining the success of an ad in any country or region. The ability to identify which elements and/or moments of an ad that contributes to its success is how economies of scale are maximised. Once one knows what works in an ad, that idea or ideas can be imported by any other market. Market research measures, such as Flow of Attention, Flow of Emotion and branding moments provide insight into what is working in an ad in any country or region because the measures are based on the visual, not verbal, elements of the ad.[22]

Trends

With the dawn of the Internet came many new advertising opportunities. Popup, Flash, banner, Popunder, advergaming, and email advertisements (the last often being a form of spam) are now commonplace.

The ability to record shows on digital video recorders (such as TiVo) allow users to record the programs for later viewing, enabling them to fast forward through commercials. Additionally, as more seasons of pre-recorded box sets are offered for sale of television programs; fewer people watch the shows on TV. However, the fact that these sets are sold, means the company will receive additional profits from the sales of these sets. To counter this effect, many advertisers have opted for product placement on TV shows like Survivor.

Particularly since the rise of "entertaining" advertising, some people may like an advertisement enough to wish to watch it later or show a friend. In general, the advertising community has not yet made this easy, although some have used the Internet to widely distribute their ads to anyone willing to see or hear them.

Another significant trend regarding future of advertising is the growing importance of the niche market using niche or targeted ads. Also brought about by the Internet and the theory of The Long Tail, advertisers will have an increasing ability to reach specific audiences. In the past, the most efficient way to deliver a message was to blanket the largest mass market audience possible. However, usage tracking, customer profiles and the growing popularity of niche content brought about by everything from blogs to social networking sites, provide advertisers with audiences that are smaller but much better defined, leading to ads that are more relevant to viewers and more effective for companies' marketing products. Among others, Comcast Spotlight is one such advertiser employing this method in their video on demand menus. These advertisements are targeted to a specific group and can be viewed by anyone wishing to find out more about a particular business or practice at any time, right from their home. This causes the viewer to become proactive and actually choose what advertisements they want to view.[23]

In freelance advertising, companies hold public competitions to create ads for their product, the best one of which is chosen for widespread distribution with a prize given to the winner(s). During the 2007 Super Bowl, PepsiCo held such a contest for the creation of a 30-second television ad for the Doritos brand of chips, offering a cash prize to the winner. Chevrolet held a similar competition for their Tahoe line of SUVs. This type of advertising, however, is still in its infancy. It may ultimately decrease the importance of advertising agencies by creating a niche for independent freelancers.
