Advertising, as the name implies, is to publicize, that is, to inform the general public of something. In terms of its meaning, advertising can be divided into broad and narrow sense. Advertising in a broad sense refers to the non-profit-oriented advertising, such as government announcements, announcements and statements of political parties, religions, education, culture, municipalities, social organizations, etc. In the narrow sense, advertisement refers to the profit-oriented advertisement, usually referring to commercial advertisement, or economic advertisement. It is the means by which industrial and commercial enterprises communicate commodity or service information to consumers or users through advertising media in a paid way in order to promote commodities or provide services. Commodity advertising is such economic advertising.
 
The word advertisement, according to textual research is a foreign language. It derives from Latin advertere, which means to notice, induce and disseminate. In Middle English (c. 1300 -- 1475), it came to mean 'to bring something to someone's attention', or 'to inform someone of something so as to draw attention to it'. It was not until the end of the 17th century that large-scale commercial activity began in England. At this time, the word advertising will be widely popular and used. At this time "advertising", no longer refers to an advertisement, but refers to a series of advertising activities. The concept of a stationary thing, the noun beer, was given a modern meaning and became "Advertising". The word kanji advertising originated from Japan.
