Advertising in Tokyo, Japan, (2005)
**Advertising** is how a company encourages people to buy their products, use their services, or adopt their ideas. Advertising is one element of marketing, which also includes design, research, and data mining.

An advertisement (or an "ad" for short) is usually designed by an advertising agency for a sponsor or brand and made public by various media. Ads appear on television, radio, newspapers, magazines, and billboards in streets and cities. Advertisers use methods that attract attention.

Advertisers influence our emotions by techniques that include stereotyping and targeting the audience: who we are. Emotions are influenced by our occupation, beliefs, personality, self-esteem, lifestyle, relationships, friends, how we look, and what we wear.

History

Commercial messages and political campaign displays have been found in the ruins of Pompeii and ancient Arabia. Lost and found advertising on papyrus was common in Ancient Greece and Rome. Wall or rock painting for commercial advertising 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 BC.

Londoner Thomas J. Barratt (1841–1914) has been called "the father of modern advertising". He worked for the Pears Soap company, eventually becoming its chairman. Barratt created an advertising campaign for the company products. It used targeted slogans, images, and phrases. One of his slogans, "Good morning. Have you used Pears' soap?" was famous in its day and into the 20th century.

Barratt introduced many of the crucial ideas that lie behind successful advertising, and these were widely circulated in his day. He constantly stressed the importance of a strong and exclusive brand image for Pears and of emphasizing the product's availability through saturation campaigns. He also understood the importance of constantly reevaluating the market for changing tastes and mores, stating in 1907 that "tastes change, fashions change, and the advertiser has to change with them. An idea that was effective a generation ago would fall flat, stale, and unprofitable if presented to the public today. Not that the idea of today is always better than the older idea, but it is different – it hits the present taste."

As the economy expanded across the world 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.
Very important was the growth of mass media, with mass circulation illustrated newspapers in the later 19th century followed by movies, radio and television.

Types of advertising
--------------------

Advertising happens in many different ways. Many products are advertised on television, although not all channels permit advertising. The advertisements usually appear during breaks between a television show. They are usually for products, other television shows, or movies. These ads are not normally much longer than 30 seconds. Some radio stations have audio advertisements that play between programmes.

An advertisement for a movie is called a trailer. It shows a short collection of clips from the movie, and shows the date it will be released in cinemas.

Advertising also takes place on websites. These may appear as "banner ads" or "popups". They are often non-moving images or flash animations[*needs update*]. The owner of the website will get money when a user clicks on the advertisement. Sometimes they will get a percentage of the money if they buy a product.

Billboards advertise products on highways and city streets. These may simply be freestanding billboards or may be part of street furniture such as a bus shelter. Buses and taxis are often covered in adverts, while budget airlines sometimes allow advertising inside their planes. Adverts also appear in newspapers, magazines, and sports programmes. Many sport stadiums have adverts set around them. Sports teams, tournaments, television programmes and public events may have a sponsor who is the main or, sometimes, only advertiser.

Techniques
----------

Advertisers use many different techniques to get people to notice their adverts, often using shocking or sexy images on purpose. Once advertisers have managed to make people notice their advert, they need to 'sell' the product or brand. They may try to make the product look appealing, however, often, advertisers use humor in such a way that gets people to remember the brand without actually promoting the product. Poor adverts can damage sales or spoil a brand's identity.

Regulations
-----------

Advertising is often strictly regulated, for example, in the United Kingdom it is illegal to advertise tobacco, except in the shop where it is sold and this is also restricted. In France, it is illegal to advertise alcohol, meaning that when many European football teams play in France, they cannot play in their usual shirts as breweries often advertise on sports shirts. It is also illegal to advertise on some television channels, the BBC in the United Kingdom and RTE in the Republic of Ireland are not allowed to permit advertising and instead make their revenue from selling a compulsory television licence. Some countries, such as Canada, regulate misleading advertising and labelling to try to prevent deceptive practices and protect consumers.
