Advertising may be categorized in a variety of ways, including by style, target audience, geographic scope, medium, or purpose. For example, in print advertising, classification by style can include
display advertising (ads with design elements sold by size) vs. classified advertising (ads without design elements sold by the word or line). Advertising may be local, national or global. An ad campaign may be directed toward consumers or to businesses. The purpose of an ad may be to raise awareness (brand advertising), or to elicit an immediate sale (direct response advertising). The term
above the line (
ATL) is used for advertising involving mass media; more targeted forms of advertising and promotion are referred to as
below the line (BTL). The two terms date back to 1954 when
Procter & Gamble began paying their advertising agencies differently from other promotional agencies. In the 2010s, as advertising technology developed, a new term,
through the line (TTL) began to come into use, referring to integrated
advertising campaigns.
Traditional media oil , London in 1877 Virtually any medium can be used for advertising. 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 and
forehead advertising, magazines, newspapers, town criers, sides of buses, banners attached to airplanes ("
logojets"),
in-flight advertisements on
seatback tray tables or overhead storage, taxicab doors, roof mounts and
passenger screens, musical stage shows, subway platforms and trains, elastic bands on disposable diapers, doors of bathroom stalls, stickers on fruit in supermarkets,
shopping cart handles (grabertising), in
streaming audio and video, posters, and on event tickets and supermarket receipts. Any situation in which an "identified" sponsor pays to deliver their message through a medium is advertising. ;
Television: Television advertising is one of the most expensive types of advertising; networks charge large amounts for commercial
airtime during popular events. The annual
Super Bowl football game in the United States is known as the most prominent advertising event on television – in 2013 it attracted an audience of over 108 million and studies have shown that 50% of those tune in to see the advertisements. The 2025 game attracted an audience of over 123 million, with a thirty-second ad costing US$8 million.
Virtual advertisements may be inserted into regular programming through computer graphics. It is typically inserted into otherwise blank backdrops or used to replace local billboards that are not relevant to the remote broadcast audience. This technique is especially used in televised sporting events.
Virtual product placement is also possible. An
infomercial is a long-format television commercial, typically five minutes or longer. The name blends the words "information" and "commercial". The main objective in an infomercial is to create an
impulse purchase, so that the target sees the presentation and then immediately buys the product through the advertised
toll-free telephone number or website. Infomercials describe and often demonstrate products, and commonly have testimonials from customers and
industry professionals. ;Radio:
Radio advertisements are broadcast as radio waves from a transmitter to an antenna and thus to a receiving device. Increasingly radio is transmitted via the internet. Airtime is purchased from a station or network in exchange for airing the commercials. While radio has the limitation of being restricted to sound, proponents of radio advertising often cite this as an advantage. According
Nielsen Media Research data published by the
Radio Advertising Bureau, 82% of people in the US aged 12 and older listened to terrestrial radio in a given week, in 2022. ;Online: Online advertising is a form of
promotion that uses the Internet and
World Wide Web for the expressed purpose of delivering marketing messages to attract customers. Online ads are delivered by an ad server. Examples of online advertising include contextual ads that appear on
search engine results pages,
banner ads,
pay per click text ads,
rich media ads,
Social network advertising,
online classified advertising,
advertising networks and
e-mail marketing, including
e-mail spam. A newer form of online advertising is called
Native Ads; which go in a website's news feed and are supposed to improve user experience by being less intrusive. However, some people argue this practice is deceptive. ;Domain names: Domain name advertising is most commonly done through pay per click
web search engines, however, advertisers often lease space directly on domain names that generically describe their products. Domain name registrants can be easy to identify through
WHOIS records that are publicly available at registrar websites. Domain name advertising was originally developed by Oingo (later known as Applied Semantics), one of
Google's early acquisitions. ;
Product placements: This is when a product or brand is embedded in entertainment and media. For example, in a film, the main character can use a branded product, such as in the movie
Minority Report, where
Tom Cruise's character John Anderton uses a branded
Nokia phone and wears a watch engraved with the
Bulgari logo. Another example of product placement 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
James Bond films, most notably
Casino Royale. In "
Fantastic Four: Rise of the Silver Surfer", the main transport vehicle shows a large
Dodge logo on the front.
Blade Runner includes some of the most obvious product placement; the whole film stops to show a
Coca-Cola billboard. ;Print: Print advertising describes advertising in a printed medium such as a newspaper, magazine, or trade journal. This encompasses everything from media with a very broad readership base, such as a major national newspaper or magazine, to more narrowly targeted media such as local newspapers and trade journals on very specialized topics. One form of print advertising is
classified advertising, which allows private individuals or companies to purchase a small, narrowly targeted ad paid by the word or line. Another form of print advertising is the display ad, which is generally a larger ad with design elements that typically run in an article section of a newspaper. Sheltered outdoor advertising combines outdoor with indoor advertisement by placing large mobile structures (
tents) in public places on a temporary basis. The large outer advertising space aims to entice the observer in, with the product promoted inside. ;Novelties (promotional products): Advertising printed on small, tangible items such as coffee mugs, T-shirts, pens, and bags is commonly referred to as
promotional merchandise, historically known as advertising novelties or advertising specialties. Industry commentary has noted a shift in the sector from low-cost giveaway items towards more purpose-driven, brand-aligned products intended to support broader marketing strategies and long-term brand development. ;Celebrity endorsements: Advertising where a celebrity endorses a product and a brand leverages celebrity influence, fame and popularity to gain recognition for their products or to promote specific stores' or products. Advertisers often advertise their products when, for example, celebrities share their favorite products or wear clothes by specific brands or designers. Celebrities are often involved in advertising campaigns, appearing in television, digital and print adverts to advertise brands and their products. The use of celebrities to endorse a brand can have disadvantages, as mistakes, poor behaviour or controversy involving the celebrity can be detrimental to the
public relations of a brand. Celebrities such as
Britney Spears have advertised for multiple products including Pepsi, Candies from Kohl's, Twister, NASCAR, and Toyota. ;
Aerial: Using aircraft,
balloons or
airships to create or display advertising media.
Skywriting is a notable example. Drones are now used for aerial advertising. aircraft in the special
Blue Man Group livery (D-LZFN) of
Friedrichshafen used for advertisement
New media Advanced advertising is
data-driven advertising, using large quantities of data and precise targeting and measurement tools. Advanced advertising makes it easier for companies who sell ad space to attribute customer purchases to the ads they display or broadcast. Increasingly, new media approaches are overtaking "traditional" media such as television, radio and newspaper as people shift to using the internet for activities such as reading, watching or listening to the news. Online advertising began with unsolicited bulk e-mail advertising known as "
e-mail spam". Spam has been a problem for e-mail users since 1978. As new online communication channels became available, advertising followed. The first banner ad appeared on the World Wide Web in 1994. Internet advertising allows companies to target specific audiences, which can improve return on investment. The rise of the internet resulted in people using
search engines to find websites and the emergence of search engine advertising, as companies sought to advertise to consumers online.
Google was founded in 1998 and by the early 2000's had become the most widely used search engine. In 2000 Google launched
AdWords, which allowed advertisers to bid, in order for their adverts to appear in paid search results. Their auction bidding system used factors such as
click-through rate and relevance, with advertisers using high quality ads rewarded with better ad placements and lower
costs per click (CPC). In online display advertising, display ads can generate awareness quickly. Whereas search requires someone to be aware of a need, display advertising can drive awareness of something new, without previous knowledge. Display can work well for direct response. Online display advertising is not only used for generating awareness, it can also be used for direct response campaigns. Mobile phones became a new mass medium in 1998 when the first paid downloadable content appeared on mobile phones in Finland,
mobile advertising followed, first launched in Finland in 2000. In 2007, the value of mobile advertising was expected to be $3 billion, with most of this generated via mobile search and video. By 2025 this had increased to an estimated market size of $262 billion. More advanced mobile ads include banner ads, coupons,
Multimedia Messaging Service picture and video messages, advergames and various
engagement marketing campaigns. One feature driving mobile ads is the
2D barcode (QR code) which replaces the need to type web addresses, and uses the camera in mobile phones to access web content. 83 percent of Japanese mobile phone users are active users of 2D barcodes. Some companies have proposed placing messages or corporate logos on the side of booster
rockets and the
International Space Station. An advertising method has emerged called "ARvertising", which uses
augmented reality technology. The emerging technology of
drone displays has been used for advertising purposes. The internet has also had a significant impact on how people watch TV, with many people now choosing to stream TV content at a time that is convenient to them. This is particularly true of people in younger age groups, with 50% of streaming viewers being aged 35 or less. In the UK, less than half of 16-24 year olds were watching traditional TV in an average week, in 2023-2024. As a result, companies are increasingly using
connected TV (CTV) to advertise, with this being one of the growing media channels. In 2024, it was suggested that ad spend in this class of media was increasing by almost 20% each year, with this type of advertising offering increased targeting opportunities, to improve effectiveness. The emergence of social networking sites such as Facebook,
Instagram, Twitter/X and
TikTok has led to companies increasingly using social media for advertising. In 2024, global social media advertising spend was expected to be $247 billion, a 14.3% year on year increase. In 2025,
Alphabet,
Meta and
Amazon controlled more than 50% of all advertising spend (globally, excluding China). These technology companies are able to invest heavily in
AI optimisation and creative automation which can improve advertising campaign effectiveness and they all have a first-party data infrastructure.
Crowdsourcing The concept of crowdsourcing has given way to the trend of
user-generated advertisements. User-generated ads are created by people, as opposed to an advertising agency or the company themselves, often resulting from brand sponsored advertising competitions. For the 2007 Super Bowl, the Frito-Lays division of
PepsiCo held the "Crash the Super Bowl" contest, allowing people to create their own
Doritos commercials.
Chevrolet held a similar competition for their Tahoe line of SUVs. Another example of companies using crowdsourcing successfully is the beverage company
Jones Soda that encourages consumers to participate in the label design themselves. This trend has given rise to several online platforms that host user-generated advertising competitions on behalf of a company. Founded in 2007, Zooppa has launched ad competitions for brands such as Google,
Nike,
Hershey's,
General Mills,
Microsoft,
NBC Universal, Zinio, and
Mini Cooper. Crowdsourcing remains controversial, as the long-term impact on the advertising industry is still unclear.
Globalization 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, maximizing 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. 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 contribute to its success is how
economies of scale are maximized. 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. == Purposes ==
